The only visible marking is "1" on the back of the tube at the breech. The three-stage barrel is smoothbore and is designed to take a 10 gauge blank shell like the popular Winchester signal cannons. Since it does not appear to be designed for use with actual live ammunition aside from blanks, it should be considered a non-firearm item in most areas, but please check your local laws. Most of the metal is nickel plated brass.

Very good with 85% plus original nickel plating remaining, a frosted appearance on most of the nickel, some brighter areas, mild scratches and dings, and aged patina on the visible brass. The firing mechanism can be a bit finicky but functions. Provenance: Dr. Gerald Klaz collection.
