O. Mustad & Son of Oslo, Norway produced the 3257 B as part of its Mustad-Barbless Hooks. The box front documents a No. 8, quality 3257 B, in 100-count. The hook carries a turned-down tapered eye, a Limerick bend, heavy (1X heavy) round wire, and a bronzed finish.
The defining feature is the manufactured barbless construction. In place of a cut barb, the wire carries a formed kink ahead of the point, printed on the box as Kink instead of barb. Image 3 shows this kink clearly as a raised set in the wire behind the point rather than a filed barb.
The box is a rigid manufacturer box with a lid, printed in black on a green ground with a floral border and the Mustad key-and-brand device. Absence of a barcode and the Oslo address place production before the mid-1970s. As a Mustad industrial product the model is not scarce, but the barbless kink construction and complete original box give it interest to collectors of Mustad packaging and to fly tyers who study early barbless patterns.

Turned Down Tapered Eye | Limerick | Heavy Wire | Bronzed | Barbless
The barbless holding function is provided by a kink formed in the wire behind the point rather than by a cut barb. Removing the barb eliminates the metal displacement of a filed barb, which some tyers of the period associated with easier penetration and reduced tearing on release. The formed kink adds a small raised set in the wire to resist the hook backing out. The turned-down tapered eye reduces bulk at the head and seats the eye in line with the pull for wet fly and nymph work. Heavy (1X heavy) round wire gives the sunk fly the mass to fish below the surface.

O. Mustad & Son originated in Norway and grew into a large industrial manufacturer of fish hooks distributed worldwide. The firm operated from Gjovik and was associated with the Oslo address on its packaging. Mustad mechanized hook production at scale, offering a wide catalog of quality numbers spanning fly, bait, and commercial patterns. The key-and-brand device printed on this box is a Mustad trademark used across many product lines.
No barcode on the box, a strong indicator of production before 1974. The address is given as Oslo - Norway; the firm used the Oslo name from 1925 onward, so this is post-1925 and does not narrow the lower bound tightly. The green letterpress label with floral border and the key-and-brand device is consistent with Mustad boxes of the mid-twentieth century. Manufactured barbless hooks with a formed kink were a mid-century Mustad offering. Combined, the evidence points to roughly 1950-1970, hedged. I
Long before catch-and-release became a widespread ethic, Mustad sold hooks that carried no barb at all. The 3257 B replaced the cut barb with a small kink formed in the wire, printed plainly on the box as Kink instead of barb. The idea was that a bend set into the wire could resist the hook backing out without the metal displacement of a filed barb. The green letterpress box, with its floral border and the Mustad key device, is a study in mid-century Norwegian packaging.
The Mustad 3257 B was intended for wet fly and nymph tying in standard trout sizes. The turned-down tapered eye and standard shank suit sunk patterns fished on the swing or dead-drifted. The manufactured barbless construction, achieved with a kink in the wire in place of a cut barb, addressed the tyers and anglers of its period who wanted a hook that penetrated and released without the tearing associated with a raised barb. Historical application centers on trout and grayling in rivers and stillwaters.
Small wet fly and soft hackle patterns; light nymph dressings.

| Hook | Match Quality | Notes |
|---|---|---|
| Mustad C49S / equivalent barbless wet-nymph hook | Moderate | Modern manufactured-barbless wet/nymph hooks approximate the intent, though bend family and eye taper differ from the vintage 3257 B. |
Rated 7.0/10 — a mass-produced Mustad model held up by the interest of an intact original box and the early manufactured-barbless kink construction, with industrial production volume as the main limiting factor.
Collector interest rests on two points: the complete original manufacturer box, which is rarer than a card and carries the Superior line printing and the Kink instead of barb text, and the manufactured barbless construction that appeals to tyers who study early barbless patterns. Boxes survive less often than loose hooks, and a full 100-count intact box commands a premium over the card equivalent.
The rating is limited by Mustad industrial production volume; the model is not scarce in absolute terms, and Mustad numbers rarely exceed the mid-range on scarcity alone. Condition is the main value driver here: the box shows toning, edge losses, tape, and a sample hook affixed to the label, which places it in good rather than excellent condition. A clean, untaped box with a full sealed count would sit toward the high end.
Rigid two-piece manufacturer box with a separate lid, constructed of tan pulp board and covered on the top face with a printed green label. Print is black letterpress on the green ground with a repeating floral/asterisk border on all four sides. Text reads: Key Brand (with the Mustad key device), O. MUSTAD & SON, Manufacturers, Oslo - Norway, Qual. 3257 B, Superior, Mustad-Barbless Hooks, Kink instead of barb, T. d. tapered eye, Bronzed, 100, No. 8, Made in Norway. A handwritten pencil 100 appears near the count field. No barcode present. A sample hook and a strip of cellophane tape are affixed to the label face.
Low ($15): good condition box, toned label with edge losses and tape, count not verified.<br />
High ($40): excellent/near-mint box, clean label, verified full 100-count.<br />
Premium factors: intact lid and label printing, full hook count, barbless kink construction, Superior line printing, no tape or annotation.<br />
Platforms: eBay US and UK, specialist tackle dealers and fairs.<br />
Confidence: E estimated — no model-specific sold data supplied; range reasoned from Mustad boxed-hook comparables.
eBay US and eBay UK vintage tackle listings; specialist tackle dealers; tackle collector fairs. Mustad boxed hooks appear regularly; boxed barbless numbers are less common than standard cards.
Confirm the quality number reads Qual. 3257 B and the line reads Mustad-Barbless Hooks with Kink instead of barb. Verify the eye line reads T. d. tapered eye and the finish line reads Bronzed. Check for absence of a barcode as a pre-1974 indicator. On the hook, look for the formed kink in the wire behind the point in place of a filed barb.
