Record summary

The Mustad-Atlantic 31010 ST is a tinned saltwater and bait hook manufactured by O. Mustad & Son in Norway during the mid-20th century. This size 3/0 specimen follows Mustad’s marketed “Limerick Hook” designation and displays the angular bend geometry commonly associated with industrial Limerick-pattern saltwater hooks of the era. The straight ring eye and relatively heavy wire are characteristic features of Mustad’s post-war saltwater production.

The hook carries the original green-label retail card identifying the model as “Qual. 31010 ST,” with “Superior” point designation and “Cadm. & Tin.” finish notation. The surviving packaging and hook configuration are consistent with Mustad export-market production from approximately the 1950s through early 1970s.

Finish
Tinned — Inferred (photographically likely) Specimen hooks are bright with no observable corrosion or patina. Tinned finish shows minor surface scratching consistent with handling and age, but plating integrity appears complete. Card shows light tan toning and minor creasing at edges; green label is fully legible with no fading or water damage. Two hooks appear to be missing from the original 100-count card (98 present), consistent with typical incomplete vintage card finds. Overall condition: Very Good.

The superior point design uses a near-straight inner taper from barb to tip, creating a moderately acute angle and a relatively flat inner face. This geometry provides good hook-setting efficiency and is less prone to blunting than hollow points when used with hard-mouthed saltwater species or tough bait presentations. The forged shank and heavy wire gauge (approximately 0.045″-0.055″) deliver strength for larger baits and abrasion resistance in rocky or kelp-filled saltwater environments. The ringed eye (straight ring) provides a simple, strong connection point with minimal snag risk — a pragmatic design choice for working-tackle users.

Historical context

mustad

O. Mustad & Son was founded in 1832 in Gjovik, Norway, and became one of the world’s largest hook manufacturers by the mid-20th century. The company’s industrial capacity and international distribution network allowed them to dominate the saltwater and commercial fishing hook markets. During the 1950s-1970s, Mustad’s Oslo and Gjovik factories operated at peak production, exporting to retailers, tackle shops, and sporting goods companies across North America, the United Kingdom, and continental Europe. The tinned and cadmium-plated finishes used on the 31010 line reflect Mustad’s investment in corrosion-resistant coating technologies, marking a shift from older bronzed and blued finishes toward modernized saltwater specifications.

Series History

The Mustad-Atlantic line represents Mustad’s branded product family sold through sporting goods retailers and department stores in North America. The 31010 ST variant (Superior point, Tinned finish) was introduced during the 1950s as part of a broader product rationalization effort, assigning model codes to specific point/finish combinations. The “Quality” designation on the packaging reflects Mustad’s competitive positioning against Partridge, Allcock, and British Redditch makers — the term indicated reliable industrial production and rust-resistant finishes for working anglers. The model remained in production through the 1960s and likely into the early 1970s, when barcode labeling began replacing hand-written price markings on tackle cards. No documented successor code is currently recorded; the model appears to have been discontinued as Mustad’s product line consolidated in the 1970s.

Era and Packaging Dating

No barcode present — strong pre-1974 indicator. Green-label packaging uses offset print method with sharp, consistent color registration typical of 1950s-1970s production. The price marking visible on the packaging (25¢ handwritten on kraft paper label) is consistent with mid-1960s retail pricing. The typography and ornamental border design on the green label match Mustad catalogs and sales literature from c. 1955-1965. The notation 'Cadm. & Tin.' and 'Made in Norway' on the label reflects post-war quality-marking practices, indicating production after 1950. The overall condition and packaging style (cardstock construction, paper quality, ink saturation) align with Mustad's documented mid-century product runs. Conservative dating: c. 1955-1970, with highest probability c. 1960-1968.

Cadmium Plating and the Post-War Saltwater Boom

The 'Cadm. & Tin.' notation on this card documents a significant industrial shift in hook finishing. Cadmium plating was widely adopted by Mustad and other manufacturers after World War II as the standard for saltwater hooks. The underlying science was sound: cadmium creates an extremely corrosion-resistant barrier superior to simple tinning or nickling alone. However, what seemed like a permanent solution became problematic decades later when environmental and occupational health concerns about cadmium emerged in the 1970s-1990s. By the 2000s, cadmium plating was restricted or banned in many countries. Today, collectors of vintage hooks from this era hold specimens treated with a process that is no longer permitted in many manufacturing contexts — making these mid-century Mustad cards inadvertent documents of industrial chemistry transitions.

Cross-reference & comparisons

Bait Fishing Saltwater

Primary Application

The 31010 ST was designed for saltwater bait fishing and commercial fishing applications where strength and corrosion resistance were paramount. The heavy-gauge wire and tinned finish made it suitable for casting live and dead baits for striped bass, bluefish, larger catfish, and other hard-fighting saltwater species. The straight-ring eye facilitated quick line attachment, and the Limerick bend provided reliable hook-setting and reduced line-twist — critical features when deploying multiple baits or working in strong current. The superior point (near-straight inner taper) delivered moderate penetration without the edge bluntness risk of hollow points when fishing tough-mouthed prey.

Secondary Applications

Light saltwater spinning and conventional casting; large freshwater bait presentations for pike and muskie (in regions where the model was available)

Classic Fly Patterns

Not typically used for fly tying.

Modern Equivalents

HookMatch QualityNotes
Mustad 92620 Beak Moderate Similar saltwater application and heavy wire, but Beak bend family is distinct from Limerick; modern equivalent in product line
Tiemco 800S Moderate Straight-ring, tinned saltwater hook in modern format; similar gap and wire gauge but different bend profile

Collector notes

Rated 2.5/10 — common in the vintage market due to Mustad's massive production volumes. Original packaging in good condition adds modest appeal, but the model was never rare and large surviving stock remains available. Collector demand is casual, driven primarily by Mustad catalog documentation and saltwater-fishing nostalgia rather than scarcity or specialist interest.

Reference value $3 – $12 USD estimate
Packaging condition Good — moderate wear, legible Recorded specimen
Packaging format MAS-01 Catalog code

The 31010 ST is abundant in the vintage tackle market, particularly in larger sizes (2/0 through 5/0), making it an accessible example for beginning collectors. What drives limited collector interest is the authenticity of mid-century Mustad branding and the visual appeal of the original green-labeled packaging. Larger sizes (3/0, 4/0) are more frequently encountered than smaller variants, but even the largest sizes do not command significant premiums.

Condition factors that most affect value are packaging integrity (card presence and legibility of the green label) and hook count completeness. A card with all 100 hooks intact and packaging showing only light toning sells for more than one with missing hooks or water-stained cardstock. Sealed, never-opened cards are extremely rare for this model and would command a notable premium if found. The tinned finish itself adds modest value over bronze or bright variants, as tinned saltwater hooks hold greater appeal to working anglers and heritage saltwater-fishing collectors.

Limiting factors include the sheer abundance of Mustad hooks in general circulation, the lack of any collaborator or designer significance, and the industrial character of the model — it was never a specialist hook favored by particular schools of tying or regional traditions. Complete original boxes (if any exist) would exceed the value of loose cards, but no box format examples are currently documented.

Packaging

Cardstock sales card, approximately 5.25" × 3.5" (13.3 × 8.9 cm), kraft paper stock in cream/tan color. Centered green label (approximately 4" × 2.5" / 10.2 × 6.4 cm) with black printed text and decorative black asterisk border. Label text reads: 'KEY BRAND / O. MUSTAD & SÖN / Manufacturers / Oslo - Norway / Qual. 31010 ST / Superior / Mustad-Atlantic Limerick Hook / 100 / No. 3/0 / Ringed / Cadm. & Tin. / Made in Norway.' Cardstock shows light toning and age-darkening consistent with 60+ years storage. No barcode. Black kraft label in upper right corner marked 'SPORTS 25¢' (handwritten price in blue ink). Card layout follows standard Mustad format of the era: hooks arranged in two columns, secured with thin wire or thread through shank eyes. Original tissue wrapper (if any) not present. Offset printing; color registration is sharp and consistent.

Preservation

Storage and Preservation

Store the card in a cool, dry environment away from direct sunlight and humidity. The tinned finish is more corrosion-resistant than bronzed finishes, but prolonged moisture exposure will eventually cause white oxidation. Keep the card flat in an archival-quality box or document storage container; avoid stacking heavy items on top, which can warp the cardstock. Original packaging is a significant portion of the value — do not remove hooks from the card unless absolutely necessary for use. If the card becomes damp, allow it to air-dry slowly at room temperature; rapid heating can cause the glue to fail and hooks to shift. The handwritten price label should be preserved as-is; do not attempt to clean or remove it, as it is part of the era documentation. Store away from ferrous metals to prevent galvanic corrosion, and keep in a location where temperature and humidity remain stable year-round.

Marking Analysis

Handwritten Markings

A handwritten price tag in blue ink marking ’25¢’ is visible on a kraft paper label affixed to the upper right of the cardstock. The script is consistent with mid-1960s retail pricing and pen style. The price point ($0.25 for 100 hooks) is typical of 1960-1968 sporting goods retail, supporting the era dating to the 1960s. The handwriting appears to be retail-applied at the point of sale, rather than a manufacturer marking, and represents the original shelf price. This is a valuable era indicator and should be preserved exactly as-is.

Primary Source

Label Analysis — Manufacturing Specifications

Source: Green label, Mustad 31010 ST original packaging card

The green label on the original packaging provides explicit manufacturing documentation: ‘Qual. 31010 ST Superior Ringed Cadm. & Tin. Made in Norway.’ This translates to: Quality model 31010, with Superior point and Ringed (straight-ring) eye. The abbreviation ‘Cadm. & Tin.’ means Cadmium and Tin plating — a two-stage corrosion-resistant finish common on saltwater and bait hooks of the 1950s-1970s era. Cadmium plating (now restricted in many countries) was used as an undercoat; the tin topcoat provided the bright silver appearance and final corrosion barrier. This dual-plating process was more expensive than simple tinning or nickling, indicating this was marketed as a premium saltwater product. The notation ‘Made in Norway’ confirms Oslo/Gjovik factory origin and was required for export compliance. The 100-count specification and card format indicate this was distributed through sporting goods retailers and department stores rather than being a mail-order specialist product.
