I was out metal detecting at my parents house, and found an old toy cannon i had that i thought i threw out. Im trying to figure out more on it, but i found a brass replica on ebay listed that has the same markings as this one, just not as clear. I dont believe this one is brass, but its some sort of non-ferrous metal. I also believe this might be a replica. I really am not sure what other resources to use in identification. I have attached pics and a link to the one i found on ebay.
