In 30 years on collecting I have only seen 2 of these. It is an extremely hard to find cast iron Zeppelin-shaped firecracker cannon from the 1920s or 1930s. This one has almost all of its original paint. Firecracker would be placed underneath and you could insert a small ball or marble in the top hole and it would fire like a cannon. I am sure it was very dangerous! It measures 3.25″ long and weighs close to a pound. One hundred percent guaranteed this is an old piece. It has never been reproduced and even finding a picture online of one is close to impossible.
