Vintage Signal Cannon. Estate Find. Condition is Used. Im not sure how this cannon works - I’m not an expert. Untested. The buyer accepts full responsibility for the use and care of this product. Selling for display only - it would make a nice desk sized display piece. The cannon itself is made of metal- nice and well made. Unknown maker; not sure how old it is. The carriage is made of wood with black paint color. Approximate length of cannon w/out the carriage is 10 15/16 inches; bore is 1/4 inch; bore length is 9 15/16 inches. Please enlarge each photo for a closer look for details and judge for yourself the condition. Thank you.
