Summary

Mustad Qual. 93400 is identified on original Key Brand packaging as a “Mustad-Carlisle” hook made in Norway. The documented hooks have a straight ringed eye, long plain shank, rounded Carlisle bend, curved-in hollowed point, short barb, and bronzed finish. P

A surviving sales/display card carries sample hooks marked 5/0, 4/0, 3/0, 2, 3, 4, 10, 12, and 20, plus a handwritten “3191.” The meaning of that handwritten number is not established. P

Packaging marked “Oslo – Norway” can date no earlier than 1 January 1925. The available documentation does not establish a narrower production period. V

IMG-1Mustad 93400 Box and Hooks Size 3 Mustad 93400 box with two photographed hooks. The label identifies them as Mustad-Carlisle Hooks, Ringed Bronzed, and Made in Norway.

How to identify it

Identify 93400 by the printed “Qual. 93400” line together with “Mustad-Carlisle Hooks,” “Point curved in,” “Ringed Bronzed,” and “Made in Norway.” Key Brand packaging carries the key trademark. P

The documented sales card also carries purple stamped size numbers and a separate handwritten “3191.” The handwritten number should not be treated as a printed model designation. P

Sizes Shown on the Sales Card

The sales/display card shows nine mounted samples marked 5/0, 4/0, 3/0, 2, 3, 4, 10, 12, and 20. These are documented display sizes; the card does not by itself establish the complete manufactured size range for model 93400. P

Pattern history and manufacturer context

Series

The documented packaging identifies model 93400 as “Mustad-Carlisle Hooks” and specifies a curved-in point, ringed construction, and bronzed finish. A sales/display card shows nine sample sizes from 5/0 through 20, but the card does not establish the complete manufactured size range. P

Design lineage

Current Mustad documentation identifies model 3191 as a Carlisle bait hook with a long shank, ringed eye, bronze finish, needle point, kirbed point, and forged construction. V A direct succession from 93400 to 3191 is not established by the available documentation.

Dating

Packaging printed “OSLO - NORWAY” can date no earlier than 1 January 1925, when the city’s official name changed from Kristiania to Oslo. V The available documentation does not establish an upper date or a narrower production interval.

O. Mustad & Son — Packaging identifies O. Mustad & Sön as manufacturer and Norway as country of origin. The “Oslo - Norway” wording dates the documented packaging to 1925 or later. V Read the maker’s history →

Use

Primary application

The documented 93400 packaging identifies the Carlisle pattern and its construction but does not state an intended fishing application.

Collecting and buying

2 / 10CollectabilityRarity: Common

Rated 2.0/10. A current size 20 listing remained active after 63 sold, indicating continuing availability; the available evidence does not establish specialist collector demand or model scarcity. V

Basis: A current size 20 eBay listing remained active after 63 sold. No documented production limit, survival count, or specialist-market evidence establishes scarcity. V

A current eBay size 20 listing remains active after a cumulative 63 sold at an asking price of $13.99. That provides evidence of continuing availability rather than scarcity. V

No documented production limit, survival count, or specialist-market evidence supports a scarce or rare classification. The condition and completeness of the photographed box and sales card are specimen attributes and do not alter the model rating.

Market value

Insufficient recorded sales data to estimate a reliable value.

0 sold observations recorded; 2 are needed, with the basis and date of the range, before a value is shown. Asking prices are shown as asking prices only.

No numeric value range is supported by transaction-level sold results in the available evidence. A current size 20 listing asks $13.99 and shows 63 sold, but the listing does not provide individual completed-sale prices. V

Handwritten Markings and Stamps

The sales card carries purple stamped size designations: 5/0, 4/0, 3/0, 2, 3, 4, 10, 12, and 20. A separate dark handwritten notation reads “3191.” The available documentation does not establish the meaning of that handwritten number. P
