At The Horse Soldier Shop, POC for these is Sam Small, the CEO, a friend. This shop is probably the “biggest” Civil War store in the US. The cannons are small ship’s cannons called “Gunades.” I’m not involved in these items, just posting pictures ‘cause I thought you might like to peek. I dont know anything about the particular founder who signed the larger cannon but I’m sure they were in the British Isles somewhere in early to mid-19 th C. The carriages included are reproductions, very few original wood carriages survive. Larger cannon is about 40” long overall, and the tube weighs about 350 lbs.
