I have been hitting a few shows in the s.Ohio and E. Indiana area. Not a lot of doubles show up at these shows. I hit the Indy 1500 as few weeks ago. Mostly all black guns. One nice table of doubles. But the owner really liked them. I did pick up a nice little takedown leather case for small bores. And a Ithaca sun shine recoil pad. Mostly the same guys selling the same stuff at a different venue.
We do have the Ohio Gun Collectors though. Stock full of doubles as a rule. After hitting the clubs shows its hard to go to others. Still have not seen a lot of buying going on there though. Mostly window shoppers and tire kickers. I picked up a elsie 16 at the last show for a reasonable price.
