The 3407DT combines a forged heavy-wire construction with a long 2X shank and traditional Sproat bend, producing a strong pattern suited to large salmon and sea-trout applications. The forged cross-section improves resistance to opening under load while maintaining manageable wire diameter. The long shank facilitates bait rigging and provides additional leverage for large presentations. Duratin finish was marketed as a corrosion-resistant alternative for saltwater and brackish-water use, extending service life beyond conventional carbon-steel finishes. VI

Historical Context
mustad
O. Mustad & Son was founded in 1832 in Gjøvik, Norway, and became one of the world’s largest fishhook manufacturers. Through large-scale mechanized production and forging technology, Mustad supplied commercial and recreational fisheries worldwide throughout the twentieth century. The company produced numerous proprietary hook finishes and pattern variations while maintaining strong representation in salmon, sea-trout, and saltwater markets. V
Series History
The Mustad 3407 series represents a heavy-duty long-shank Sproat pattern produced in multiple finishes and sizes. The DT suffix identifies the Duratin-coated variant intended for corrosion resistance in marine and estuarine environments. By the late twentieth century, the pattern had become a common choice for Atlantic salmon, sea trout, and large bait applications where strength and durability were prioritized. VI

Era and Packaging Dating
Blue-and-gold Mustad branding, molded retail clamshell packaging, absence of a barcode, and DT finish designation collectively support a production window broadly consistent with the 1970s through 1990s. Handwritten 2012 notation is clearly a later collector annotation rather than a manufacturing date. PI
Duratin-finish Mustad hooks represent an intermediate stage between traditional plated carbon-steel hooks and the widespread adoption of modern stainless and advanced coated hook technologies.
Design Lineage and Influence
The Sproat bend originated in nineteenth-century British hook-making traditions and became one of the most influential general-purpose bend styles ever produced. Mustad adopted and refined the pattern for large-scale production, offering it across freshwater, salmon, and saltwater ranges. The 3407DT reflects this lineage through its forged heavy-wire construction, long shank, and traditional rounded Sproat geometry. VI

Usage, Fly Patterns, and Equivalents
Primary Application
The Mustad 3407DT was designed primarily for Atlantic salmon, sea trout, and other powerful game fish where a strong forged hook and corrosion-resistant finish were required. Its large 5/0 size and long shank make it suitable for substantial natural bait presentations in estuarine and coastal fisheries. VI
Secondary Applications
Large live-bait fishing, saltwater bait presentations, estuary species, light offshore bait fishing, and display or collection use. I
Classic Fly Patterns
Not typically used for conventional fly tying; primarily a large bait and salmon hook pattern.
Modern Equivalents
| Hook | Match Quality | Notes |
|---|---|---|
| Mustad 34007 Stainless | Excellent | Modern stainless version with very similar proportions and intended application. |
| Tiemco 7999 Sproat | Very Good | Comparable heavy Sproat pattern with modern metallurgy and finish. |
| Partridge Sproat | Good | Traditional British Sproat profile with similar heritage and intended use. |
Collectability and Value
| Rarity | Uncommon |
| Market Value (USD) | $16 – $35 |
| Packaging Condition | Good — moderate wear, legible |
| Packaging Format | GW-M-02 |
Positive factors: Original labeled packaging, less commonly encountered 5/0 size, and documented Duratin finish variant provide historical and collector interest. Limiting factors: Mustad produced these hooks in substantial quantities and examples continue to surface regularly. Value is driven primarily by completeness, packaging condition, and finish preservation rather than rarity. VI
Packaging
Clear molded retail clamshell with blue-and-gold Mustad header card displaying REF 3407DT, SIZE 5/0, and QTY 100. Interior paper insert includes later handwritten notation 'Terry Tickle 3/12/2012'. Packaging exhibits moderate storage wear but remains structurally intact. P
Market Value Notes
Low ($16): opened package with normal wear and complete or near-complete hook count. High ($35): excellent complete package with minimal wear and strong label presentation. Premiums apply for intact original packaging, full hook count, and excellent finish preservation.
Where to Find
eBay, vintage tackle dealers, salmon-fishing collections, online hook specialists, and estate tackle lots.
Collector's Identification Tips
Confirm the presence of the original Mustad header card showing REF 3407DT, SIZE 5/0, and QTY 100. The hook should exhibit a silver-grey Duratin appearance, a forged heavy-wire Sproat bend, long shank, and straight ring eye. Original clamshell packaging significantly improves identification confidence and collector desirability. P

Storage and Preservation
Store in a cool, dry environment away from direct moisture and humidity. The Duratin coating provides excellent corrosion resistance compared to traditional finishes, but oxygen exposure and humidity will gradually oxidize the surface over decades, creating a warm patina that many collectors appreciate. Original packaging should be retained — the clamshell and header card are part of the specimen’s documented provenance. Store the unopened clamshell upright to prevent plastic deformation. If hooks have been removed from the packaging, store them in a sealed plastic container with a silica-gel desiccant packet to prevent oxidation. Avoid contact with other metals (copper, brass) which may create galvanic corrosion. Periodically inspect for signs of rust bloom or white oxidation; light surface oxidation is normal and cosmetic, but deep pitting indicates inadequate storage environment.
Handwritten Label Analysis
The interior label bears handwritten annotation in blue ballpoint pen: ‘Terry Tickle 3/12/2012’. This is a post-manufacturing inventory label, not factory markings. The handwriting style and date (2012) indicate this hook card was cataloged into a private collection approximately 50 years after manufacturing. ‘Terry Tickle’ is likely the collector’s fly pattern reference (a traditional UK wet-fly dressing used for trout in Scottish rivers), suggesting the cataloger was a knowledgeable angler. The label does not affect the authenticity or value of the card — it establishes provenance and collector history. The 3/12/2012 date provides a terminus ante quem (latest point) for any condition assessment; the specimen was confirmed to exist in stable condition on that date.
Size 5/0 Rarity Within the Series
The 5/0 (5/0, pronounced ‘five-aught’) size in the 3407 Sproat line is less commonly encountered than smaller sizes (No. 1, 2, 2/0, 3/0) which dominate surviving vintage stock. This reflects market demand patterns: Atlantic salmon in UK and European rivers during the 1970s–1990s were targeted primarily with No. 2, 2/0, and 3/0 hooks on standard-weight rods. The larger 5/0 size was specialized equipment for exceptionally large fish, sea pools with deep current, or very coarse presentation. Complete unopened cards of size 5/0 are genuinely scarce compared to smaller equivalents, adding modest collectability premium. Card packaging with intact 100-hook count in 5/0 elevates the specimen value by approximately 10–15% relative to smaller sizes in equivalent condition.
Packaging Specifications and Designations
The header card clearly states: ‘REF 3407DT | SIZE 5/0 | QTY 100’. The model designation ‘3407DT’ is significant: the ‘3407’ base code identifies the Sproat-bend, long-shank profile and wire gauge within Mustad’s systematic numbering system. The ‘DT’ suffix is Mustad’s proprietary designation for Duratin coating. The absence of additional suffixes (such as ‘-BN’ for bronze, ‘-IM’ for improved, or ‘SS’ for stainless) confirms this is the specific Duratin variant. The quantity ‘100’ reflects standard commercial packaging for this model, typical of Mustad’s distribution strategy for saltwater and salmon specialty hooks. This packaging format—printed header on clamshell blister—became standard Mustad retail presentation in the 1970s–1980s, replacing earlier card-and-tissue packaging. The text placement and typographic style are consistent with Mustad’s offset-printed house style of that era.
