Believed to have been manufactured by the Naval Company of Doylestown, PA. this cannon uses a Hotchkiss style sliding breech for loading, spring loaded firing pin, and a lanyard-operated hammer. The carriage is unmarked, but otherwise nearly identical to the standard production model produced by the Naval Company. Mounted on a wooden display base. Formally from the collection of noted firearms expert and author Frank Sellers, who stated that he had received the cannon from the Winchester factory collection, in exchange for evaluation services.

Excellent with most of the black paint finish remaining. There is some water spotting on the base. The original lanyard is present.
