How to identify it

Without the packaging, identify the hook by the point and barb described in the technical notes. No other identifying mark is documented for this model.

One barb on the inner face, just behind the point P. It stands off the wire at roughly 30 to 45 degrees E; its length is not measurable here.

Dark brown to black on the shank and upper face P. The outer bend and the area under the point are brighter gold-brown, with scratches on that band P.

OBS-7IMG-2IMG-3
ConstructionForgedOBS-4

The point turns in toward the shank line, the in-turned beak point that the label describes as à pointe rentrante P. The tip looks sharp at this scale P.

The label describes the hooks as forged (Forgés). The flattened band on the bend fits that description, though the forging itself is not visible I.

The shank is plain, with no slices, bait-holder marks or stamped markings P.

Size 3 and Vintage Hook Sizing Systems

Mustad’s modern beak hook chart (product 92671) lists size 6 at 20 mm and size 8 at 16.5 mm in total length, with no size 3 V. This size 3 length falls between those modern sizes E.

Vintage and modern numbering may differ, and this entry does not establish how the 530 series numbered its sizes. Size 3 is the only size documented for this model.

Specimens, packaging, and label

This record documents one specimen. It describes that specimen only, not every example of the model.

The size designation rests on the handwritten numeral alone. Two hooks appear in one photograph, and they look alike in outline, eye position and barb placement at this scale P. The container is probably a box or sleeve I, and no view shows the hooks inside it.

Care of this specimen: Keep the packaging dry, since the top edge already shows a stain-like patch. Limit handling of the bright band on the bend, which already shows fine scratches.

Condition

No rust, pitting or spotting is visible at this scale P. Point tips and barbs look intact, and the bright band on the bend shows fine scratches P.

Pattern history and manufacturer context

Series

The printed code Qual. 530 B appears on the label P. The B suffix is read as the bronzed finish I.

No catalog, dated price list or production record for the 530 series has been found, so its dates, finishes and size range are not established.

Design lineage

Other Mustad beak hooks, including the 92641-BR, are sold under separate numbers V. No source documents a line of descent from the 530 B to them.

Dating

The city was called Kristiania (Christiania) until 1 January 1925, when the name became Oslo V. Christiania was the official spelling before 1877 and stayed in use after it, so the printed name gives an upper bound of 1924, not a start date V. The front panel shows no barcode P, but the back is not photographed, so the packaging date is inferred I.

O. Mustad & Son — O. Mustad & Son traces its roots to 1832 at Vardal and was headquartered in Gjøvik V. Hook making was industrialized in 1877 V. Read the maker’s history →
Keeping the Machine Secret. Mustad and its inventor Mathias Topp kept the hook machine secret rather than patenting it, restricting access and using non-disclosure agreements V.

Use

  • Nymph
  • Bait fishing

Primary application

No source documents how this model was fished, and bait use is inferred from the hook’s form I.

Fly patterns

No fly-tying use is documented for this model.

Collecting and buying

No collector rating is given for this model. No completed sales, catalog listings or counts of surviving examples have been documented.

Scarcity and collector demand cannot be rated from the sources on file. No completed sales of the 530 B have been documented, and no catalog lists the model.

The condition of the packaging photographed does not set a rating for the model. That condition is described in the specimen notes.

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 completed sales for this model have been documented, so the figure shown does not rest on sales. Asking prices are not used as a basis.

A seller lists Mustad reference 530 in sizes 6 and 7 on eBay. No listing for the 530 B card has been found.

Label and source analysis

Handwritten Annotations

The size designation rests on one handwritten numeral, since the printed text gives no size P.

The ink and writing tool cannot be determined from the photograph I.

Label Text and Nomenclature Analysis

Source: Printed label on the front panel of the packaging

Hameçons means hooks, Forgés means forged, Ronds means round, and Bronzés means bronzed. À pointe rentrante means with an in-turned point.

Première Qualité means first quality. Renvérés, in the phrase anneau Renvérés, is not translated here because its exact sense is not established.

Qual. 530 B reads as the code 530 with a B suffix. Reading B as the bronzed finish is an inference I.
