5Pattern history and manufacturer context
Series
The surviving package identifies Qual. 3411 as “Mustad-O’Shaughnessy Hooks” and gives a quantity of 100. V An archived marketplace record independently identifies exact model 3411, size 2/0, as O’Shaughnessy blind-eye hooks in a 100-hook box. V
These records establish model identity and a documented packaging format, but they do not establish introduction or discontinuation dates.
Design lineage
The documented 3411 combines the O’Shaughnessy designation on the package with a blind, marked terminal on the specimen. VP No predecessor, successor, or dated model lineage is established by the available evidence.
Dating
The label says “OSLO • NORWAY,” which places this package no earlier than 1925. V Key Brand hooks were advertised in Field & Stream by April 1932, so the trademark does not confine the package to postwar production. V No source in the record establishes a closing production date.
O. Mustad & Son — Mustad's official history places its mechanized hook works near Gjøvik and dates the Hook Maker to 1877. The company says it represented about half of global hook production in the 1950s.
V Read the maker’s history → Key Brand Before World War II. The Key Brand mark does not by itself indicate postwar production. Mustad advertised Key Brand fish hooks in Field & Stream in April 1932. V
7Collecting and buying
7 / 10CollectabilityRarity: Scarce
A collectability rating is not supportable from the available exact-model scarcity and demand evidence.
Basis: One archived exact-model marketplace record is documented, but no listing frequency or survivor count is available; rarity remains unverified. V
One archived marketplace record documents an exact Qual. 3411 size 2/0 in a 100-hook box. V A current listing for 3411A size 5/0 documents market activity for a related variant, not for Qual. 3411 itself. V
No source in the record establishes listing frequency, surviving population, or collector demand for Qual. 3411. A rating of 5.5 or higher therefore lacks the required scarcity basis, and a lower rating cannot be assigned confidently from the available evidence.
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 qualifying exact-model sold-price observations are recorded. The 3411A listing is a related variant, and the archived 3411 record does not supply a sold price. V
Where to find
Exact-model availability is not established. An archived Trout Underground marketplace record documents a 100-hook box of Qual. 3411 size 2/0. V
