This cannon appears to be a one-of-a-kind handmade item executed by a very skilled craftsman. Included is a business card for Frank's Repair Shop with "Builder of the cannon" written on the back and photos of the build process. Barrel of the cannon is approximately 22" long with a caliber being approximately 1" diameter. The overall measurements are approximately 33" wide at the trunnions and 34" long. Very fine showing some wear mainly on the wheels due to rolling.
