Photographic record

4 photographs

Lid of a yellow and green box printed FALCON KIRBY FISH HOOKS 100, with a bird of prey in the centre and ASSORTED X139A JAPAN along the bottom line.
IMG-1Falcon — New entry — image 1 Lid top of the Falcon Kirby X139A box: 100 hooks, assorted sizes, marked JAPAN. The corners show wear and paper loss.

How to identify it

The lid carries FALCON KIRBY in an arched title above a bird of prey, with FISH and HOOKS either side of it and 100 beneath each P. A centred block below reads HIGHEST QUALITY, UNIFORM IN SIZE and FILED POINT ~ RINGED. The bottom line reads ASSORTED, X139A and JAPAN P.

The side panel repeats the name and adds 100, BRONZED and RUST PROOF P. The photographed hook shows no stamped marking on the shank or eye P.

A dealer lists a Falcon Kirby box with the same wording and the code X139A V. A Keystone Kirby box from Japan, coded X 139B, uses the same filed-point and ringed wording V. Check both the brand name and the code.

Show noteHide note

Box prints BRONZED and RUST PROOF P. The photographed hook is dark olive-brown metallic with gold and copper highlights and a mottled sheen P.

LBL-10OBS-8

The photographed hook has a straight, plain shank with no kinks, ridges or bait-holder slices visible P. The wire looks round in section, and the point is filed down from it I. The point is long and tapering, with file facets along the flanks P.

The point lies in the same plane as the rest of the hook in plan view, so no offset is evident I. A plan view cannot rule out a slight offset.

The shank proportion is nearest the 2X long group in the site’s catalog comparison I.

Corners are worn with paper loss, edges are frayed and there are small chips; the label field is intact P. A small dark speck right of RUST PROOF resembles an apostrophe and is stray ink or dirt P. Only the lid top and one side panel are photographed, and no photograph shows the hook inside the box, so the pairing is probable, not certain.

Pattern history and manufacturer context

Design lineage

A current manufacturer’s guide describes Kirby hooks as having a round bend and an offset point V. In this reference, a kirbed point is offset to the left, seen from the eye looking down the shank.

The name Kirby is printed as the product name on the box P. No source located ties X139A to an earlier pattern or a named maker.
