Unfortunately I have just picked up a nice, older S&W M12 and have my eyes open for an M-1 Carbine so the Thompson will have to wait. I have already told my wife that part of my 401K is fenced for this.
Thanks for the info and the differences between the old and new models. I had a chance to purchase a new model but passed because I really want an older version. Unless my financial situation changes radically, I will pass on the drums. However, if I DO win the lottery, all bets are off.
