Oh Yeah! Plenty of affordable stuff, regular guns and deals. I've never seen any black guns though. This is where collecting gets inspiration and gets started. The downer on this stuff is the old timers bought or got this stuff for nothing, found it, inherited it or robbed a widow. Keep that in mind when negotiating.
"regular guns"? Not sure what that is. To some that would be a modern firearm (non C&R)
There are restrictions on what can be sold. No post 1898 handguns and I have rarely seen anything that was not C&R.
Lots of historical collectables so if you want civil war, Great War, WWII "stuff" you will see plenty here.
I have 2 field glasses I got at previous shows.
