Record summary

The Mustad 3406 B represents a crucial chapter in saltwater hook development, serving as the direct predecessor to the legendary 34007 stainless steel model. Manufactured by O. Mustad & Søn in Oslo during the 1950s-1960s, this forged O’Shaughnessy pattern features heavy wire construction and nickelplated finish for corrosion resistance in marine environments P.

The hook’s Superior point geometry provides reliable penetration while the classic O’Shaughnessy bend distributes fighting stress evenly along the curve, making it nearly impossible to straighten under load. Originally packaged in distinctive red-labeled boxes with the iconic Key Brand logo, these hooks were widely used for classic New England streamers and inshore bait fishing V.

Era dating is confirmed by the ‘Oslo – Norway’ designation and characteristic mid-century packaging style, placing production firmly in the pre-stainless transition period. The ‘B’ suffix likely indicates the nickelplated variant within the 3406 series, distinguishing it from other finish options available at the time I.

The forged construction flattens the wire’s cross-section, significantly increasing strength without adding weight. The O’Shaughnessy bend geometry distributes stress mathematically along a parabolic curve, preventing straightening under extreme loads. The Superior point features a near-straight inner taper that concentrates penetrating force at the tip while maintaining structural integrity – a crucial balance for heavy saltwater applications where both sharpness and durability are essential P.

Historical context

O. Mustad & Son

Read the maker’s history →

Series History

The 3406 series emerged during Mustad’s mid-century push into specialized saltwater patterns, designed to bridge the gap between traditional freshwater hooks and the demanding requirements of marine angling. The ‘B’ designation specifically indicated nickelplated finish, offering corrosion resistance before stainless steel became economically viable for mass production. This series directly evolved into the famous 34007 stainless model, maintaining identical geometry while upgrading the metallurgy for superior saltwater performance.

Era and Packaging Dating

Oslo - Norway designation indicates post-1925 production. Red paper label with snowflake border pattern and Key Brand logo are characteristic of Mustad's mid-century packaging before plastic sleeves and barcodes in late 1970s. Letterpress printing and box construction consistent with 1950s-1960s era.

Irish Geometry, Norwegian Precision

The O'Shaughnessy bend is named after the hook maker who popularized it in Limerick, Ireland, but Mustad's industrial precision manufacturing made it globally dominant. Interestingly, the nickelplating process used on the 3406 B required specialized electrolytic baths and was considered premium technology in the 1950s, costing significantly more than simple tinning or japanning finishes of the era.

Cross-reference & comparisons

Bait Fishing Saltwater

Primary Application

Designed for saltwater fly fishing and heavy bait applications. The O’Shaughnessy bend provides exceptional strength for fighting large fish, while the nickelplated finish offers corrosion resistance in marine environments. Popular for classic New England streamers, bucktails, and inshore bait fishing for species like flounder, snapper blues, and striped bass P.

Secondary Applications

Collector notes

Solid collectability driven by historical significance as predecessor to the famous 34007 stainless model. Limited by relatively common availability.

This hook represents an important transition point in Mustad’s saltwater hook evolution, serving as the direct predecessor to the legendary 34007 stainless model. The nickelplated finish and vintage packaging appeal to collectors of mid-century tackle. However, collectability is constrained by the hook’s utility focus and relatively wide distribution during its production run. The ‘B’ designation and Norwegian manufacturing add modest historical interest I.

Packaging

Cream-colored cardstock box with bright red paper label featuring decorative snowflake border (repeated asterisk motif) in black. Label text in heavy black letterpress: 'Key Brand' with skeleton key graphic (upper left), 'O. MUSTAD & SÖN' (line 1), 'MANUFACTURERS' (line 2), 'OSLO - NORWAY' (line 3), 'Qual. 3406 B' (line 4), 'Superior' (line 5), 'Mustad-O'Shaughnessy Hooks' (line 6), 'Forged' (line 7), 'Ringed Nickelplated' (line 8), 'Made in Norway' (lower right). Size marked as 'No. 1' or 'No. 4' in lower left with quantity '100'.

Market Value Notes

Full boxes in very good condition command premium pricing. Individual hooks or partial boxes significantly less valuable. Red label packaging adds 20-30% value over plain boxes.

Where to Find

eBay vintage tackle listings, tackle swap meets, estate sales of saltwater anglers

Preservation

Storage and Preservation

Store hooks in original packaging when possible, as the vintage red label adds significant collector value. Keep in a cool, dry environment to prevent corrosion of the nickelplated finish. While nickelplating offers good corrosion resistance, prolonged moisture exposure can cause pitting and discoloration. Avoid contact with dissimilar metals to prevent galvanic corrosion. If hooks show early signs of corrosion, light polishing with fine compound can restore the finish, though this may reduce collector value.

Label Text Analysis

Source: Original Mustad 3406 B packaging label, photographed specimen

The label text ‘Ringed Nickelplated’ confirms both the eye construction and finish treatment, while ‘Made in Norway’ emphasizes the Norwegian manufacturing origin during Mustad’s industrial dominance period. The ‘Superior’ designation on line 5 follows Mustad’s standardized labeling hierarchy, indicating premium point geometry rather than quality grade. The snowflake border pattern and letterpress printing are characteristic of Mustad’s mid-century packaging aesthetic, designed for global recognition in multiple markets.
