You bet. They usually set up a large tent at Civil War Re-enactments around the country and have all sorts of neat stuff for sale including BP Guns, Leather Gear, Uniforms, etc. I saw them in Illinois years ago and grabbed a business card.
I bought that Pietta, Holster, spare cylinder box, and a fork tongue belt from their website.
The only thing I wasn't impressed by was the belt. The buckle is nice but the belt is rough (unfinished) leather on the back side.
The holster and cylinder box are good quality for the price.
