Marked on the barrel as "Falcon Model 337 Custombilt 410 ga - 2 3/4 In - Choke - Full," this shotgun carries clear origin and configuration details. The receiver bears the Falcon bird-head logo, and the left side shows the U.S. importer stamp "SPESCO CORP ATL GA" along with "MADE IN JAPAN," confirming its Japanese manufacture and U.S. import history.
The action is a top-lever break-open design with an exposed hammer and a single trigger. An extractor is present for case removal, and there is no auto-ejector. Capacity is one round, consistent with its single-shot design.
The 26-inch plain, round steel barrel has a fixed full choke and no rib, optimized for tighter patterns in .410 bore. The chamber is cut for 2 3/4 inch shells, and the overall finish is blued on both barrel and receiver.
Stocked in hardwood, the shotgun has a pistol-grip, straight-comb buttstock and a long beavertail forend with a black cap ring. The ventilated recoil pad features a black line spacer and a molded game-bird motif. Length of pull measures 14 inches.
Construction is all steel for the barrel and receiver, finished in blued. The combination of Japanese manufacture, Falcon branding, and Spesco importer markings makes this Model 337 Custombilt a clearly identified example of its type.
