Summary

The Horrocks-Ibbotson Grade 552 package identifies the product as “CARLISLE FISH HOOKS,” No. 1, packed 100 ringed, and made in Germany. The label also carries the UTICAN diamond trademark and the printed claim “RUSTPROOF.” V

Photographed specimens have long straight plain shanks, fixed closed eyes, deep rounded bends, single barbs, and long tapered points with a visibly concave inner surface. Their surfaces are dark brown to bronze-colored with localized wear. P

The checked evidence does not establish a production date, the German factory that made the hooks, or a documented fishing application.

How to identify it

Identify this Grade 552 first by the package. The front label reads “CARLISLE FISH HOOKS,” “100 RINGED,” “No 1,” “GRADE 552,” “HORROCKS-IBBOTSON CO. UTICA,N.Y.,” and “MADE IN GERMANY.” A blue diamond UTICAN trademark appears at right. V

The photographed hooks have long plain shanks, fixed closed eyes approximately in line with the shank, deep rounded bends, and concave inner point surfaces. No separate loose ring is present at the eye. P

The photographed specimens use fixed closed eyes formed at the end of long, straight, plain shanks. Each has a single barb and a long tapered point with a visibly concave inner surface. P

Specimen S1 retains physical-caliper ranges of 46.2-47.2 mm overall length, 31.5-33.5 mm shank length, 9.7-10.7 mm gap, 17.3-19.3 mm bend depth, and 1.14-1.40 mm wire diameter. These ranges are carried forward as estimates in the checked record. E

For database classification, the silhouette comparison places bend position nearest Limerick and wire thickness nearest Standard. The package itself names the product “CARLISLE FISH HOOKS.” V

Condition

Photographed hooks are structurally intact with scratches, scuffs, and small bright worn areas. No extensive red rust or heavy corrosion is visible. P

Pattern history and manufacturer context

Series

The photographed package documents a German-made Horrocks-Ibbotson Grade 552 in No. 1, marked “100 RINGED.” V

A separate FlyHooks.org record also uses number 552 for a Horrocks-Ibbotson hook attributed to Mustad of Norway, reference 3191, in sizes 10 through 2. That record does not match the German-made No. 1 package, and the relationship between the two uses of 552 remains unresolved. V

Design lineage

The package identifies the pattern as “CARLISLE FISH HOOKS.” An 1896 Edward vom Hofe catalogue independently uses “CARLISLE RINGED” for Carlisle hooks with fixed closed eyes, showing that “ringed” was established period eye terminology. V

Dating

No barcode present (strong pre-1974 indicator). Letterpress printing method and paper stock consistent with 1920s-1940s manufacturing. 'Made in Germany' attribution typical of pre-WWII American tackle imports. UTICAN trademark and Utica, NY address confirm Horrocks-Ibbotson Co. distribution. Box construction and label design (die-cut fish, color palette, typography) align with 1920s-1940s American tackle packaging. Burgundy ink and cream stock typical of this era. No postal ZIP code visible — address uses city and state only, typical of pre-1963 packaging.

Horrocks-Ibbotson — The package identifies Horrocks-Ibbotson Co., Utica, N.Y., and states MADE IN GERMANY. The checked evidence does not identify the German manufacturer or establish a production date. V Read the maker’s history →
Ringed Carlisle Terminology. An 1896 Edward vom Hofe catalogue used “CARLISLE RINGED” for Carlisle hooks with a fixed closed eye. That period usage helps interpret “100 RINGED” on the Grade 552 box without assuming a separate swivel ring. V

Use

Primary application

The surviving package identifies the product only as “CARLISLE FISH HOOKS.” It does not state a bait, freshwater, saltwater, streamer, or other intended fishing application. V

Collecting and buying

4 / 10CollectabilityRarity: Uncommon

Rated 4.0/10 — uncommon but not scarce; moderate collector interest driven by label design and German-American trade history. The Grade 552 survives in modest quantities, primarily as complete original packages with intact labels. Scarcity is driven by packaging fragility and age toning rather than production rarity. Collector demand is primarily from label and trade-history specialists rather than functional hook tyers.

What makes this hook collectible: The Grade 552 appeals to several collector constituencies: (1) Horrocks-Ibbotson company historians and trade-mark collectors seeking UTICAN-branded examples; (2) label-design enthusiasts attracted to the die-cut fish illustration and burgundy letterpress printing; (3) German-American trade-history researchers documenting inter-war hook imports; (4) general vintage tackle collectors seeking unusual house-brand offerings from regional distributors.

Limiting factors: The Grade 552 was a budget product in its era, manufactured in volume as part of a commodity supply chain rather than as a specialty or prestige item. German industrial production was consistent and reliable, meaning surviving examples are not exceptionally rare. The model lacks attribution to a famous designer or exclusive origin story. No direct connection to a named fly pattern or legendary angler enhances its appeal. Post-WWII, the model was discontinued and superseded by Mustad and American domestic alternatives, so no nostalgic user base maintains demand.

Most desirable variants: Complete original packages with intact labels command the highest premium. Sealed or near-sealed boxes are exceptionally scarce. The No. 1 size is the most commonly encountered, making other sizes (if they exist) potentially more collectible. Packages with pristine label printing and minimal age toning are strongly preferred; heavily aged or faded labels reduce value substantially.

Condition factors affecting value: Label integrity is paramount — a clean, bright label with sharp printing and minimal toning can double the value of an opened package. Missing hooks reduce value by 5-10% per missing hook. Water staining, foxing, or mold spots on the label significantly diminish appeal. Loose or detached rings on the eyes are acceptable but slightly reduce value. Original tissue wrapping, if present and intact, adds 15-20% premium. A sealed package commands a 40-50% premium over an opened equivalent.

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.

Low ($8): Good condition — opened package, all or most hooks present, label shows moderate to heavy age toning, edges creased, but fundamentally intact and readable.
High ($22): Excellent condition — package sealed or near-sealed, complete hook count (100), label bright with minimal toning, original tissue present and intact, no creases or tears.
Premium factors: Label brightness and legibility; intact original tissue or sealed packaging; complete hook count; sharp UTICAN trademark definition; die-cut fish illustration clarity; absence of mold or foxing.
Platforms: eBay (US and international), vintage tackle dealers, eBay UK specialists in Horrocks-Ibbotson items, regional tackle auctions.
Confidence: E estimated — limited comparable sales data; range based on similar inter-war German-import bait hook packages with house brands and strong label designs.

Where to find

eBay (search 'Horrocks-Ibbotson Grade 552' or 'UTICAN hooks'); tackle dealers specializing in vintage American imports and German hooks; regional vintage fishing tackle auctions in the Northeast; British and European eBay (where German-made vintage tackle has strong appeal). Regional tackle fairs in New York and the Great Lakes are occasional sources.
