Thompson New Englander

I have come across a LH Thompson Center New Englander 50 cal and was wondering what a true value might be? It's in like new condition never been fired. Gun broker has RH up to 400. It would seem the LH are rarer. And he has a spare LH barrel like wise
What's a good price I should offer?

just because people put those prices on their stuff at gunbroker don't mean that is 'what they go for', in fact most times they don't. nice New Englanders can be had for 200 to 250 and even with the extra barrel I personally wouldn't go over three(unless that extra barrel is a 12ga).

and the market for lefties is small so I wouldn't pay extra just for that.

my opinion & yer welcome to it. your mileage may vary.
