Re: Allen & Thurber 4" Pepperbox
Flayderman's Guide can't be considered the final authority.
Prices vary by region. And the lousy economy has brought some gun prices down, especially esoteric guns for which there are few interested buyers. I think your Allen & Thurber would qualify in this regard.
The best indicator is seeing what bidders pay on the auction sites, not what the sellers list it at.
Personally, with a missing trigger guard, I'd rethink his price. It appears to be in pretty good shape, if it works. Pepperboxes that have survived often have broken springs and parts. Finding one in good shape, that functions as it should, may be difficult.
I'd use Flayderman's as a guide, but online auctions as a better guide.
