Someone had the right idea to stretch a Stingray to appear like a rail. From what I can tell the frame is made of 3 Schwinns. A 1968 3 speed 20'' from the seat tube back. A mens 26'' front section and a Fair Lady fork. The right chainstay was also modded to accommodate a large sprocket for a derailleur setup. 3 speeds back then were 36t frames. Kudos to the frame builder whom I do not know.
