How to identify it

Look for the number ‘Qual. 57552’ and the name ‘Hameçons Ronds – Mustad’ on a gold-on-cream lid label (LBL-1). A gold skeleton key sits at the left between the words ‘Marque’ and ‘à la Clef’, and a border of snowflake-like motifs frames the label (LBL-2, IMG-1).

The box shown prints ‘No.’ without a size, and a numeral is handwritten after it (LBL-3, LBL-4). Treat the numeral as an annotation and check it against the hook.

On the hook, look for a ring eye turned down, a plain straight shank, a short cut barb and a dark olive-brown bronzed surface (OBS-1, OBS-5, OBS-6, OBS-7).

OBS-7LBL-1

The wire at the bend shows a broad flat face with a lengthwise ridge near the outer edge P. The label states ‘Forgés’ (forged), and the flat face is consistent with forged wire I. Wire thickness is nearest the standard gauge when compared with other catalogued hooks E.

The shank is plain and straight, with no ridges, kinks or markings P. Its length relative to the hook is nearest standard among catalogued hooks E.

The point tapers in a near-straight line to a fine tip, and its inner face is pitted P. Whether the inner face is concave is not resolved in the close-up.

Only the top face of a closed box is photographed; tan or peach edge bands show at left and right. The label has yellow-brown blotchy stains with tide-line edges along its upper edge, right margin and lower edge. The lid board has a round dull patch left of the label and a chipped or scuffed edge band at the upper left. Hinge, sides, base, contents and hook count are not shown. The hook photographs are assigned to this specimen as probable; nothing in them ties the hook to the box.

Pattern history and manufacturer context

Series

The lid label names the hook Hameçons Ronds – Mustad and numbers it ‘Qual. 57552’, with the line Première Qualité (LBL-1). Three further lines read Forgés Droits (forged, straight), Bronzés à oeillet aminci (bronzed, with a thinned eye) and Renforcés Spéciale (specially reinforced) (LBL-1).

Design lineage

No catalog, price list or dealer page for 57552 has been located, so the model’s size range, production dates and design lineage are not documented.

Dating

The label gives the maker's location as OSLO - NORVÈGE. Kristiania became Oslo on 1 January 1925 V, so the label was probably printed in or after 1925 I. No source consulted dates the label further.

O. Mustad & Son — Mustad traces to 1832 in Vardal, Norway, where a works made nails and steel wire. Hook production was industrialised in 1877 V. Read the maker’s history →
The Key Mark. The lid label carries a gold skeleton key between the words 'Marque' and 'à la Clef'. Mustad's brand listing includes a Key Brand V, so the mark is probably that brand I.

Use

  • Nymph
  • Wet fly

Primary application

Intended as a light to medium wet fly and nymph hook. The round kendal bend and relatively forgiving gap suit traditional dressed wets and early nymph patterns. French packaging indicates availability in Continental markets, suggesting use across European trout streams and rivers.

Mustad 3906ModerateListed with a tapered eye turned down and a straight shank (SRC-4). Current 3906 is 3X heavy wire with a sproat bend (SRC-3); 57552 falls nearest standard wire (CMP-3), so wire weight and bend differ.
