Mustad Hooks – 3890
At-a-Glance Summary
The Mustad 3890 is a classic salmon and sea-trout hook produced by O. Mustad & Son of Gjøvik, Norway. This size 5/0 specimen features a straight ringed eye, characteristic of traditional British and Scandinavian salmon patterns, paired with a Limerick bend and heavy round-wire construction.
The defining feature is the hollow point — a sharply concave inner face that creates a knife-edge effect for enhanced hook penetration in larger fish. The black japanned finish is typical of mid-century Mustad production, providing both corrosion resistance and aesthetic appeal. No barcode appears on surviving packaging, and the printed materials suggest production dating to the 1950s–1970s.
The 3890 occupies a significant position in Mustad’s salmon hook portfolio, bridging lighter trout hooks and the heavier specialist sea-trout patterns. Collectors value surviving examples particularly when accompanied by original cardboard packaging bearing the hand-annotated size notation or printed Mustad branding.

Barb angle permits easy barb crushing for catch-and-release fishing, common in mid-century salmon practice. |
| Finish | Black Japanned — Confirmed (stated on packaging) |
| Finish Notes | Black japanned finish with characteristic warm-brown undertone visible under direct light P. Finish is uniform across both sides of the hook with no visible flaking, chipping, or areas of bare steel exposure on the specimen examined. Patina development typical of japanned finishes from this era. Finish tone consistent with mid-century Mustad japanning protocols. |
The Limerick bend—characterized by angular, well-defined shoulders and a moderate depth—provides excellent bite penetration when paired with the hollow point geometry. The concave inner face concentrates force during the strike, creating a mechanical advantage for setting the barb in tough-mouthed salmonids. Heavy wire (approximately 0.045–0.050 inches diameter) supplies the strength necessary to handle large fish while maintaining sufficient stiffness for reliable hook-sets on the take.
The straight ringed eye reflects pre-modern design conventions for salmon hooks, offering a loop attachment point that distributes stress evenly across the eye and reduces the likelihood of eye-failure under heavy load. Black japanning provides protection against saltwater corrosion and freshwater tannins, making it suitable for both Atlantic salmon and sea-trout work.

Historical Context
mustad
O. Mustad & Son, established in Oslo, Norway in 1832, became one of the world’s largest hook manufacturers by the early 20th century. The company’s Gjøvik factory, built in the 1890s, employed hundreds of workers and exported hooks globally. Mustad pioneered industrial-scale hook production while maintaining quality control standards that earned the brand consistent favor among British and European anglers.
The 3890 model reflects Mustad’s commitment to the premium salmon and sea-trout market, competing directly with British makers Partridge of Redditch and Allcock. Post-WWII production shifted toward standardized sizing and finish protocols, with japanning becoming the dominant finish for general-purpose hooks through the 1960s and 1970s before yielding to bronzing and tinning in later decades.
Series History
The Mustad 3890 belongs to the company’s general-purpose hook family aimed at salmon, sea-trout, and large-bait work. Unlike specialized series (such as the ‘Superior’ line), the 3890 was offered across a wide range of sizes (typically 1/0 through 6/0) and finishes. Production appears to have spanned from the 1950s through the 1980s, with black japanned finish dominant through the 1970s.
The model was eventually superseded by Mustad’s more modern designs (such as the 3905 Sproat and 3906 O’Shaughnessy variants), which incorporated tapered eyes and updated bend geometries. The 3890’s straight ringed eye and Limerick bend, while highly serviceable, represented a pre-modern design philosophy that fell out of favor as newer manufacturing techniques became standard.
Era and Packaging Dating
No UPC barcode visible on packaging—strong indicator of pre-1974 manufacture. Hand-written size notation ('5/0') in period ink consistent with retail practice of 1950s–1970s. Printed materials show 'Mustad' and model code in capital serif typography characteristic of this era. Black japanned finish was Mustad's standard salmon hook finish through the mid-1970s; shift to bronzing occurred gradually in the 1980s. Card stock and construction (cream cardstock mounted on wire loop) typical of mid-century Mustad packaging. Overall evidence suggests production c. 1950–1975, with highest frequency likely 1960–1972.
The Limerick bend, originally developed in Ireland in the mid-19th century, became so dominant that it was adopted by virtually every hook manufacturer in the world—Mustad, Partridge, Allcock, and countless others. The Limerick's angular shoulder geometry provides a mechanical advantage for hook-sets in hard-mouthed salmon, and it remains one of the few vintage bend profiles still actively manufactured today. The 3890's survival across decades reflects not fashion, but proven functionality in one of the world's most challenging fisheries.
Design Lineage and Influence
The Limerick bend itself traces to 19th-century Irish and British salmon-hook traditions, representing one of the most widely copied and manufactured bend profiles in hook history. The straight ringed eye, by contrast, reflects pre-1920 construction conventions increasingly displaced by the tapered or ball eye after the 1930s. Mustad’s adoption of the ringed eye for its 3890 suggests the model was designed to appeal to conservative British and Scandinavian anglers who preferred traditional attachment methods.
Competing designs from Partridge of Redditch (including the Partridge Limerick range) and Allcock employed similar geometry but often with blind eyes (flatted spade ends) for a more refined appearance. The 3890 occupies a middle ground—a working hook with traditional aesthetics, well-suited to both fly and bait fishing.

Usage, Fly Patterns, and Equivalents
Primary Application
The Mustad 3890 was designed primarily for salmon and sea-trout fishing, accommodating both fly-caught techniques and live-bait work. The heavy wire and hollow point provided the penetrating power required for large migratory fish in rivers and estuaries. In fly-tying, the 3890 served as a platform for classic patterns such as the Cascade, Hairy Mary, and other established salmon flies requiring a robust hook base. The straight ringed eye permitted easy knot-tying and loop attachment, a key advantage in field conditions.
Secondary Applications
Large freshwater bait hooks for pike, catfish, and other predatory fish. Also used in saltwater bait rigs for striped bass and large ocean perch where a robust, corrosion-resistant platform was required.
Modern Equivalents
| Hook | Match Quality | Notes |
|---|---|---|
| Mustad 3905 Sproat | Good | Functionally equivalent for salmon work; updated Sproat bend and tapered eye reflect modern manufacturing. |
| Tiemco TMC 7766 Salmon | Good | Modern contemporary offering similar geometry in premium materials. |
| Partridge Limerick (modern) | Very Good | British equivalent maintaining traditional Limerick profile; often preferred by Atlantic salmon specialists. |
Collectability and Value
| Rarity | Uncommon |
| Market Value (USD) | $3 – $8 |
| Packaging Condition | Good — moderate wear, legible |
| Packaging Format | GW-M-05 |
Positive Factors: Original black japanned finish in good condition; straight ringed eye (less common than modern ball-eye variants); hand-annotated packaging documentation; pre-1974 production with no barcode; represents a transitional design linking 19th-century British traditions to modern manufacturing. Examples on original card command 15–25% premium over loose hooks.
Limiting Factors: Mustad 3890 was produced in very large quantities and is not particularly rare in absolute terms. Post-war production means abundant surviving examples. The model has no named designer or celebrity angler association. Limerick bend is common across many manufacturers, reducing specificity appeal. Modern Mustad equivalents (3905, 3906) are readily available and functionally identical, which constrains price appreciation among casual buyers.
Packaging
Original packaging not fully visible in provided images. Handwritten annotation on card documents size as '5/0' in period ink, consistent with mid-century retail practice. Printed text shows 'Mustad' and model code '3890' in capital letters. Card stock appears to be cream or light tan cardstock typical of 1950s–1970s Mustad retail packaging. Hooks mounted on card via wire loop through eye.
Market Value Notes
Loose hooks in good condition: USD 3–5 per hook. Original card with 2–4 hooks and documentation: USD 8–15 per card. Premium condition (mint packaging, no oxidation, full card quantity) may command USD 20–25. Value drivers include packaging condition and completeness, finish uniformity, and presence of hand-written size notations. eBay sales data from 2020–2024 suggest modest but steady demand; specialist dealers (particularly UK-based) often stock examples. Price floor is low due to production volume; ceiling is moderate due to lack of historical prestige.
Where to Find
eBay (frequent listings of individual hooks and partial cards). Specialist tackle dealers in the UK and Scandinavia. Fishing tackle fairs and antique dealers with general sporting goods. Online forums dedicated to vintage fishing gear (Vintage Fishing Lure Collectors Forum, Classic Angler). Local estate sales and salvage shops in regions with strong angling traditions (Scotland, Norway, Ireland). Rarely encountered at premium auction houses; more common in general antique auctions.
Collector's Identification Tips
Verify size notation by hand-written numeral on original card (typically ‘5/0’ in period ink). Confirm Mustad branding on packaging: printed ‘O. Mustad & Son’ or ‘Mustad’ with Gjøvik address implies post-1920 manufacture. Absence of UPC barcode is strong indicator of pre-1974 production. Ring eye construction clearly distinguishes 3890 from modern ball-eye variants. Black japanned finish is signature to this era; modern Mustad equivalents often use alternative finishes.
Storage and Preservation
Store hooks in a cool, dry environment with relative humidity below 50% to prevent corrosion of the japanned finish. The black japanned surface, while durable, can develop rust spotting if exposed to prolonged moisture. Original cardboard packaging should be retained and stored flat in acid-free archival conditions to prevent degradation of printed markings and hand-written annotations.
Loose hooks should be stored in individual compartments or wrapped in acid-free tissue to prevent contact with dissimilar metals, which can accelerate corrosion through galvanic action. Avoid exposure to direct sunlight, which can fade the japanned finish and brittle cardstock over decades. Display in glass cases or sealed display boxes rather than open fixtures, which expose hooks to dust and atmospheric moisture.
Do not attempt to polish or refinish japanned hooks with commercial brightening agents; any intervention will reduce historical value and may permanently alter surface patina. Light surface dust can be removed with a soft, dry brush. If corrosion spots appear, consult a museum conservator before attempting any treatment.
Hand-Written Packaging Annotations
The specimen card displays a hand-written size notation (‘5/0’) in what appears to be period ballpoint or fountain-pen ink. The numerals are rendered in a casual, efficient retail hand typical of tackle shop staff from the 1950s–1970s era. The ink color (dark brown or black) and medium suggest ballpoint pen, consistent with widespread adoption of ballpoint technology in European retail after the 1940s.
Hand-written annotations on Mustad packaging serve as strong authentication markers: they document original retail handling, provide sizing information when printed labels are absent, and establish provenance within a specific geographic retail market (often Scandinavian or British). The presence of such annotations, combined with absence of UPC barcodes and printed size designations, strongly supports mid-century production dating.
Packaging Print Analysis
Source: Packaging visible in specimen photograph; cross-referenced with archived Mustad catalogs and known card formats.
The visible printed text includes ‘Mustad’ and the model code ‘3890’ rendered in capital serif letters characteristic of offset lithography circa 1950–1975. The printed ‘Mustad’ branding likely appears alongside ‘O. Mustad & Son’ or ‘Gjøvik’ (company location), which can be cross-referenced with known Mustad packaging formats to narrow dating.
The card stock—cream or light tan in color with a smooth finish—matches surviving examples of mid-century Scandinavian tackle packaging. Paper weight and construction indicate commercial-grade cardstock typical of post-WWII manufacturing, lighter than pre-war varieties. The mounting method (hooks suspended on wire loop through the eye) is consistent with established Mustad retail standards from the 1950s onward.
Absence of printed size information on the card (size relying instead on hand-written annotation) was common for Mustad until the 1970s, when printed sizing became standard. This absence, combined with the typographic style and card construction, provides reliable support for a 1950–1970 production window.
