I build these on a seat the customer supplies. I don't do pans or foam work. I can re-upholster the seat or use the existing upholstery based on your wishes and it's condition. The customer supplies the guns, real or replica. I can give sources for replica guns.
Tony's rig is a double holster rig, fitted for Colt .45 Peacemakers, fully lined, with 12 bullet loops, fancy layered border stamping with nickel spots, and a full chap leather re-upholstery on the seat.
