Those "Duke" headstamped 32-40's were made by Winchester to go along with the "Duke" commerative rifle . There's also a "Duke" colt that is a remake of the one he carried in so many films, and they made ammo to go with it. You could get the whole thing in a boxed set, along with the "Duke" holster/belt rig if you cared to spend the money. That was 20 some odd years ago.
