Hello, Bob. Mine are Berry's, purchased from Cabellas. Mine are also intended for brass shells, I just use different media. The 2 on the bench are considered 5 lb. tumblers, that is tools & media combined weight, and the bowls are 10-1/2" in diameter, and 4" deep. The one on the floor is from Harbor Freight, 18 lb. capacity, and the bowl is 14" dia. in the center, and 7" deep. I have worn through the bowls with the metal, but I was able to repair them, and I have bought replacements as well.Regards, Lou
