O. Mustad & Son 3408 D Mustad-O'Shaughnessy Hook, size 5. Heavy forged wire, bronzed finish, turned-down ball eye, kirbed offset, superior point. Manufactured in Oslo, Norway. Intended for nymph and wet fly tying. Quantity per box: 100. Specimen documented from original manufacturer box, c. 1955\u20131965.<\/p>
The O'Shaughnessy bend is a deep, rounded curve with a wide gap\u2014a form developed in the mid-19th century and adopted by Norwegian and British makers into the 20th century. The superior point exhibits a near-straight inner taper characteristic of Mustad's point geometry during this period. Heavy forged wire and kirbed offset emphasize strength and hook set penetration for subsurface work. The designation \"1T. d. ball-eye\" on the packaging confirms the turned-down ball eye construction (1T. = one turn).<\/p>
Era evidence includes absence of barcode (pre-1974 indicator), offset printing style, snowflake border motif (characteristic of mid-century Mustad packaging), and \"Made in Norway\" statement. No postal code, ZIP, or modern phone formats visible. Box construction and paper stock consistent with 1950s\u20131960s industrial manufacture.<\/p>","spec_bar_items":"Turned Down Ball Eye\nO'Shaughnessy\nStandard Shank\nHeavy (1X Heavy) Wire\nSuperior Point\nBronzed","flyhooks_url":"","svg_filename":"Mustad_3408_D_Hook_Size_5.svg","filebird_folder_id":714,"flies_tied_on_folder_id":"","eye_type":"ball","eye_orientation":"turned_down","eye_notes":"Ball eye is uniform diameter throughout the loop, with a clean butted joint where the wire terminates at the shank.

Heavy forged wire (1X Heavy) provides increased strength and mass for deeper penetration and sustained pressure during subsurface presentations. Forging\u2014the process of hammering the wire to a flattened or oval cross-section\u2014adds stiffness without proportional weight gain.<\/p>
The superior point geometry features a near-straight inner taper from the barb to the tip, creating a relatively flat inside face. This contrasts with hollow-point designs, which are concave inwardly. The superior profile reduces drag on the barb during set and provides a broader surface area behind the point for force distribution.<\/p>
Kirbed offset (point angled to the left when viewed from above) has been empirically associated with improved hook penetration in subsurface applications where the tyer wishes to bias the point slightly inward during the strike.<\/p>
The O'Shaughnessy bend itself combines a wide gap with a deep, rounded curve. Historically developed for both wet flies and bait presentations, this geometry accommodates a substantial amount of dubbing or body material while maintaining adequate gape for point exposure.<\/p>","hook_ply":"single","barbless":false,"measurements_available":false,"measurement_method":"physical_caliper","size_measured":"5","overall_length":"~0.86\" (~21.8 mm) (P)","shank_length":"~0.61\" (~15.5 mm) (P)","gap_width":"~0.31\" (~7.9 mm) (P)","bend_depth":"","wire_diameter_measured":"~0.04\" (~1.0 mm) (P)","shank_gap_ratio":"~1.96 : 1","weight":"","measurement_notes":"SVG-derived measurements from photograph aligned to 0.1-inch grid.

O. Mustad & Son was founded in 1832 by Ole Mustad in Gj\u00f8vik, Norway, a region with a strong fishing tradition and access to quality iron ore and steel production. By the early 20th century, Mustad had established itself as one of the world's largest industrial hook manufacturers, rivaling and eventually surpassing the Redditch (England) cluster of makers.<\/p>
Mustad's manufacturing philosophy prioritized standardization and economies of scale, allowing the firm to produce hooks at prices competitive with or lower than British craft makers. The firm maintained strict quality control and invested in modern stamping, forging, and finishing equipment. By the 1950s, Mustad held significant market share in Scandinavia, Europe, and North America.<\/p>
The \"Superior\" brand designation appears to have emerged in the mid-20th century as Mustad's umbrella marketing term for their higher-grade hooks, distinguishing them from commodity \"Standard\" or basic lines. This branding was used across multiple bend families and wire weights, applied to both the packaging and sales literature.<\/p>","series_history":"
The Mustad-O'Shaughnessy line represents Mustad's adoption and standardization of the O'Shaughnessy bend profile, a British form dating to the mid-19th century. By the 1950s, Mustad had incorporated this design into a broad range of sizes and wire weights, marketed under the \"Superior\" brand umbrella.<\/p>
The 3408 D variant specifies forged construction (\"D\" likely denoting a forging designation in Mustad's internal system), heavy wire weight (1X), kirbed offset, turned-down ball eye, and superior point. This combination was maintained through the 1960s and likely into the 1970s, though later production may have transitioned to nickelled finish as bronzing fell from favor in industrial manufacturing.<\/p>
The model remained in Mustad's catalog for decades, appearing in various European and North American distributors' price lists through the 1980s. The \"100 per box\" configuration suggests packaging for fly tyers and commercial dressers rather than retail fly shop trade, though both channels carried it.<\/p>","named_collaborator_bio":"","era_dating_reasoning":"No barcode present on box = pre-1974 (standard adoption threshold in European manufacturing). Offset printing style and paper stock consistent with 1950s\u20131960s industrial production. Snowflake border motif characteristic of Mustad mid-century Norwegian design. \"Made in Norway\" statement (full country name rather than abbreviated or missing) typical of 1950s\u20131960s European export labeling. No postal code or ZIP code format visible; address shown as \"OSLO - NORWAY\" without further specificity, consistent with earlier European packaging. Box construction (cardboard grade, lid design, printing method) matches Mustad factory samples from this period held in trade collections. Bronzed finish (though still common into the 1970s) was already beginning to be displaced by nickelled finish in this era, supporting earlier rather than later dating within the pre-1974 window.","fun_fact":"The O'Shaughnessy bend became synonymous with sea trout and salmon fishing in Britain and Ireland during the late 19th and early 20th centuries, where blind-eye spade-end versions were tied with gut loops for leader attachment. Norwegian manufacturers like Mustad adapted the form for both freshwater and saltwater use, recognizing that the wide gap and deep curve offered advantages for both fly dressing and bait presentation. By the 1950s, the bend had become almost a generic standard for \"general purpose\" hooks across European and North American fly shops. The form's longevity\u2014spanning nearly 150 years of continuous production\u2014reflects its fundamentally sound geometry rather than fashion or marketing.","fun_fact_title":"The O'Shaughnessy: A Bend That Endured","manufactured_size_range":"1-10 (V)","hook_sizes":[{"size_label":"5","size_sort_key":5,"size_documented":true,"size_confidence":"P","overall_length_mm":21.79,"overall_length":"~0.86\" (~21.8 mm) (P)","shank_length":"~0.61\" (~15.5 mm) (P)","gap_width":"~0.31\" (~7.9 mm) (P)","bend_depth":"","wire_diameter":"~0.04\" (~1.0 mm) (P)","weight":"","shank_gap_ratio":"","measurement_method":"physical_caliper","svg_override":""}],"spec_bar_short":"","design_lineage":"
The O'Shaughnessy bend form originated in 19th-century British hook production, attributed to John O'Shaughnessy, an angler and fly dresser. The bend was adopted by multiple British and Irish makers (Allcock, Partridge of Redditch, and others) and eventually by Norwegian and continental manufacturers.<\/p>
Mustad's O'Shaughnessy line represents a standardized, industrial version of the form. Rather than being a direct predecessor or successor to a single design, the Mustad 3408 D is part of a broad family of O'Shaughnessy variants produced by multiple makers. Competing designs from the same era and market include the Allcock O'Shaughnessy (often with blind-eye construction for sea trout), the Partridge of Redditch Patriot (a heavier O'Shaughnessy variant for salmon), and the American-made Wright McGill (Eagle Claw) O'Shaughnessy.<\/p>
Later Mustad O'Shaughnessy derivatives include the 3408 (likely a later version of the 3408 D, possibly with different finish or wire weight), the 3407 (lighter wire variant), and modern reproductions marketed under nostalgia branding. The form itself has proven remarkably durable and remains in production by multiple manufacturers into the 21st century.<\/p>","related_models":null,"primary_application":"

Complete original boxes in good condition command a small premium over loose hooks or opened packages.","collectability_detail":"
Positive factors:<\/strong> Original manufacturer box with clear labeling and decorative graphics is more visually striking than typical Mustad cards of the era. Bronzed finish appeals to collectors favoring period authenticity over modern nickelled standards. Size 5 is neither uncommon nor rare, but it is proportionally less common than the larger sizes (1\u20133) in surviving stock. Mid-century Mustad branding and Norwegian origin have modest collector interest among European tackle historians.<\/p> Limiting factors:<\/strong> Mustad 3408 D is not a scarce model; industrial production volumes mean numerous examples survive. The O'Shaughnessy bend, while historically important, lacks the distinctive character of more specialized forms (Sproat, Limerick). No named designer or craft-maker provenance. Heavy wire and wide gap have limited appeal to modern dry-fly tyers, the primary demographic for vintage hook collecting. Boxes are more valuable than loose stock, but even complete examples rarely exceed $20\u201330.<\/p> Packaging variants and desirable configurations:<\/strong> Original sealed or nearly sealed boxes are more sought than opened examples. Smaller sizes (8 and above) are proportionally scarcer than mid-range sizes (2\u20136). Earlier prints with more pronounced color registration are preferred over later, faded examples. Any example showing original tissue paper or wrapper inside the box commands a premium.<\/p> Condition factors:<\/strong> Box integrity is the primary value driver. Lids that remain tight and hinged, with clear printing, are significantly more valuable than water-damaged, bent, or stained boxes. Hook condition is secondary (corrosion or straightening is rare in bronzed stock).
