NOS=NEW OLD STOCK. This lower was probably made in the mid late 90's for PWA Pacific West Arms, also located in Milan IL. (where LMT is) PWA went under after the ban of 94. About a year and a half ago I discovered that LMT (you were correct) had 150 or so left. (Should have bought them all) The secret, if it was one, got out. Got the last 5 I could about 8 months ago. There are none left. Absolute top quality, in finish, etc. It's new because it never left the factory. It's old because it was made several plus years ago.
