Summary

The Pflueger 5511-Br is documented from one size 7/0 hook and a torn strip of its box label. The label reads O’Shaughnessy, Ringed and Bronzed P.

No catalog entry, date or address for the number has been found, so the period of manufacture and the intended use are left open.

How to identify it

Identify the model by the number 5511-Br. with BRONZED beneath it on the right panel of the label, and by O’SHAUGHNESSY in large green capitals on the left panel P.

The size is not printed on the strip. A pencil 7/0 sits under BRONZED P.

Features of the model, as recorded

Eye in line with the shank, seen edge-on as a rounded end about 6.7 by 2.5 mm E. The opening is not visible. The label prints RINGED P.

Show noteHide note

Characteristic deep O'Shaughnessy forged bend with pronounced offset point geometry. The inner face shows the classic offset relationship, not vertically aligned with the shank. Bend depth is substantial relative to overall hook size, engineered to maximize leverage and resist straightening forces P.

PointStandard / Spear

Single cut barb lying back along the point at a shallow angle, roughly 25 to 30 degrees P. Cut root about 8.4 mm behind the tip E.

The label prints BRONZED. The hook shows dark olive-brown to bronze-green with tan highlights on raised faces and dark speckling on the point flank P.

ConstructionForgedIMG-2OBS-4IMG-1

Caliper measurements of the 7/0 specimen give a length of 2.4 in (60.96 mm) and a gap of 0.94 in (23.88 mm) P. Shank length and bend depth have no caliper record.

The photograph shows a printed grid with no stated scale. Read as 0.1 in squares, the straight shank is near 35 mm, the outer height of the bend near 27 mm, and the wire about 2 mm wide in top view E.

In the site’s catalog comparison of traced outlines, the shank proportion falls nearest the Standard category and the wire thickness nearest Fine E.

Pattern history and manufacturer context

Series

Two Pflueger numbers in opened sources pair four digits with a letter suffix: 3221-J, a ringed Kirby in 6/0 on a dealer listing V, and 3121-J, a ringed Limerick in 9/0 on a collector page V. Neither source explains the suffix.

On the 5511 label, the suffix Br. sits directly above BRONZED, which suggests it abbreviates the finish I. No opened source lists the 5511 series.

Design lineage

The O’Shaughnessy name traces to hook makers of that name in Limerick, Ireland V. An article drawing on an 1866 Limerick history names Daniel O’Shaughnessy as a leading maker about sixty years before 1866, followed by his son John and later Robert V.

Dating

The label strip carries no date, address, patent or brand-line mark P. No opened source dates this label style or the number 5511, so the period of manufacture is not established.

Pflueger — Sources date the Pflueger firm (Enterprise Manufacturing Company) to 1880 or 1881 and differ on whether Ernest F. or Ernest A. Pflueger founded it V. Shakespeare bought the Pflueger tackle division in 1966 V. Read the maker’s history →
Limerick, 1866. An article on the O'Shaughnessy hook, drawing on an 1866 Limerick history, gives Selles as the last maker at that date V.

Use

  • Saltwater
  • Bait fishing

Primary application

The label gives no intended use. By size, a 7/0 falls in the range used for salmon flies, large streamers and saltwater work I. No opened source documents an application for the 5511-Br.

Collecting and buying

3 / 10CollectabilityRarity: Common

Rated 3 of 10. Large Pflueger output (V, undated) and a dealer listing of a full box of another Pflueger number point to easy finding. No sale, catalog or survival record exists for the 5511-Br, so demand is unmeasured and the rating stays low.

Basis: Large Pflueger hook output (undated, collector source) and a dealer listing of a full box of another Pflueger number. No source records how often the 5511-Br appears.

The rating describes the model as usually found. A dealer offers a full box of 100 Pflueger 3221-J hooks, another ringed Pflueger number V.

No sold results are recorded for the 5511-Br, so the page gives no value basis.

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 sold results are recorded for this model, so no value basis is stated.

Where to find

Online dealer listings carry boxed Pflueger hooks; one is a full box of 3221-J V. No listing for the 5511-Br is recorded here.
