Hi! I found this small bronze cannon a few years ago and still have no idea where the country of origin is. I was able to determine it’s age very scientifically with great accuracy. I believe it’s from 1516 since its stamped right on there! There is no riffling. I have been trying to find info on that insignia but with no luck. Found a lot of old ballast bricks with a cross in them as well. Any ideas??
