I just found out about this auction and it looks like they have a nice double and some nice canoes.
Meissner’s Auction, New Lebanon, NY, 10/9

These guys have this ornate, German-looking double barrel shotgun coming up on Saturday. They’re calling it a shotgun, but it may be rifles. It looks like it has a set trigger.
It’s an interesting looking gun, worth checking out if you’re in the area.
You can see more pics of it here. Scroll down.
