I have the Corbin seat (Gunfighter and Lady), just looking for a back rest. If you have one that you're not using, please reply with photos and an asking price. For now, I'm scanning fleabay. Cheers!
I went with one of the fleabay back rests on mine, nowhere near as nice as the Corbin but no where the money of a Corbin either.
It's actually held up pretty well for the almost 5 years I've been using it
