I have a Corbin seat in good condition that the guy I bought my F3 off of gave me with the deal. I dont need it and I dont think it will fit on my F3. On the bottom of the seat it has F2 market on it, and is made by Corbin. Looks much like this one but not identical, Corbin seat pic . I can get some pictures of the actual seat if anyone is interested. Price $100 if picked up by a local in South Florida, or I can ship it. Sells $219 new.
