Friends Dad was a skilled trades worker for GM. He was huge into the antique bottle scene. I have no idea what his tumbler cost GM but it was an amazing unit. we tumbled at least a ton of brass in that thing back in the day haha. Buddy still has it and its absolutely the strongest and most expensive home brass tumbler ever built I nearly guarantee it. No doubt 4 or 5 departments were involved in it.
