A complete working 37mm Hotchkiss Revolving Cannon is for sale at the Cannon Superstore. The price is $95,000 and is an original 1880 gun (the ad says four barrels but I count the usual 5). The carriage is a reproduction.
Birmingham Small Arms 4/8/16
Acquired a BSA Co LTD Commonwealth of Australia 218 Mashburn Bee pistol. Serial #4990. Was told by local gunsmith that it was likely converted from rifle to pistol 100 or more years ago. Gunsmith said he had heard of those conversions but had never seen one. Any info would b appreciated.
