What kind if lever action shotgun does arnorld have in the terminator have and how much does it go for?

ummmm maybe, sawed-off winchester model 1887......its an old gun. only really made in the early 1900's. that gun could be expensive seeing now its an antique. but a replica might be cheaper, but a replica still might be expensive. I would have no clue where to find a replica. Ebay, or google it. odds are you wont find that exact gun, maybe a diff rent model, but they all look cool anyways.
