Mustad Quality 3310 is documented by a surviving “Mustad-Cincinnati Bass Hooks” label and four specimen groups identified as sizes 18, 19, 20, and 23 P. The model is a single, barbed bass hook with a blind, transversely marked shank end and bronzed finish PV.
Physical-caliper records are available for sizes 18, 19, and 20. The size 23 specimen has a grid-derived estimated overall length of about 28.9 mm and still needs caliper confirmation E.

Look for the Key Brand skeleton-key device at upper left and the repeating floral or rosette border. The printed identification includes “Qual. 3310,” “Mustad-Cincinnati Bass Hooks,” “Superior,” and “Marked Bronzed” P. On the photographed card, the size is handwritten as 19 beside the printed “No.” field.

Examined specimens have no formed ring or loop. Their straight round-wire shanks end in a short band of transverse ridges or notches rather than a visible flattened spade end P. Detailed specimens show a long-ground point with a nearly straight inner face and a small barb P.
The platform silhouette comparison classifies the bend as Sneck (CMP-2) and the wire gauge as Standard (CMP-3). Recorded caliper overall lengths are 41.33 mm for size 18, 40.16 mm for size 19, and 36.09 mm for size 20 V.

Specimen labels identify sizes 18, 19, 20, and 23 P. Physical-caliper records give overall lengths of 41.33 mm for size 18, 40.16 mm for size 19, and 36.09 mm for size 20 V. The size 23 specimen has a proposed grid-derived overall length of about 28.9 mm E.
FlyHooks.org independently documents a size 18 specimen at 43.04 mm overall, 32.9 mm shank, 15.4 mm height, and 1.25 mm wire V. Those measurements describe a different specimen and are retained separately from the physical-caliper record on this page.
We have measurements for sizes 18, 19, 20. Know any others? Submit calipered measurements and we'll review and add them. Thank you!
This record documents 4 specimens. Each describes itself only; none stands for every example of the model.
The two hooks are photographed loose below the printed card or label; they are not mounted to it.

Examined hooks are complete with intact points, barbs, and marked shanks; no heavy red corrosion is visible P. The size 19 printed card has light edge wear and toning.
The photographed Mustad label identifies the pattern as Quality 3310, “Mustad-Cincinnati Bass Hooks,” and states “Superior” and “Marked Bronzed” P. It also reads “O. MUSTAD & SÖN / MANUFACTURERS / OSLO – NORWAY” and “Made in Norway.”
The platform silhouette comparison classifies the 3310 bend as Sneck (CMP-2). No broader lineage is assigned here.
The photographed label prints “OSLO - NORWAY” P. Oslo became the official city name on January 1, 1925 V, so this packaging specimen is no earlier than 1925.
The package identifies Quality 3310 as “Mustad-Cincinnati Bass Hooks” P. FlyHooks.org independently lists the 3310 for bass use V.
Scarce and historically significant. Represents pre-eyed-hook technology and a distinct American fishing tradition. Mustad-Cincinnati Bass Hooks are modest collector interest, not commonly seen intact with original packaging.
Positive factors: Documented blind-eye construction demonstrates early snelling technology; marked shank is engineering detail of historical interest; Mustad-Cincinnati branding reflects specific regional marketing strategy; original hand-stamped card with decorative border has aesthetic appeal; pre-1960s dating with clear era evidence supports vintage collector market; represents functional fishing technology mostly abandoned after 1960s; marked shank hooks increasingly rare as collectors prefer eyed variants.
Limiting factors: No fly-tying market demand (modern tyers prefer eyed hooks); bait fishing tradition has declined relative to fly fishing; blind-eye construction requires specialized snelling knowledge; not premium rarity tier (more common than Partridge or early Edgar Sealey variants); size 19 (vintage scale) not equivalent to modern standards, limiting functional reuse; condition of original card affects value significantly, and many examples found loose without packaging.
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.
Original hand-stamped card with intact packaging commands 12–18 USD. Loose hooks alone typically 4–8 USD. Condition of orange card is primary driver: mint/excellent card can double value. Pricing reflects modest specialty-collector demand; most sales through vintage tackle dealers and eBay rather than premium auction venues. Regional North American sellers moving higher volumes than European markets.
eBay vintage fishing tackle; specialist dealers in vintage bass and catfish hooks; tackle swap meets and fishing heritage fairs; occasional estate sales with old-tackle collections.

The printed card or label reads: “Key / Brand”; “O. MUSTAD & SÖN / MANUFACTURERS / OSLO – NORWAY”; “Qual. 3310 / Superior”; “Mustad-Cincinnati Bass Hooks”; “100”; “Marked Bronzed”; “No.”; and “Made in Norway” P. The number 19 is handwritten beside the printed “No.” field. A skeleton-key device appears with Key Brand, and a repeating floral or rosette border surrounds the card.
| Hook | Match | Notes |
|---|---|---|
| Mustad 3366 Sproat Wet Fly | Very good | Same Sproat bend family and approximate size/gap. Modern ringed eye and tapered-eye versions eliminate snelling requirement. Functionally equivalent for similar bait and wet-fly applications. |
| Tiemco D2099 Sproat | Very good | Japanese manufacture, modern tapered eye, identical bend profile to 3310. Premium alternative for modern fly tying in Sproat family. |
| Partridge Limerick Blind Eye (if still in production) | Good | British maker, blind-eye construction preserves snelling tradition. Limerick bend slightly more angular than Sproat, but both serve bait and classic wet-fly work. |
