Calico 30 carbine mini antiaircraft gun kit. Absolutely complete. Assembled once to make sure all was there. Just add a pair of M1 carbines and go blasting! Would like to trade for a 45. Smaller models ok, too. PO, SA, SA MilSpec, etc. The second pic is the sister kit in .22. I might sell it, too. But, I put the pic here so you could see the completed setup. Need other views or details, LMK!
