Just picked up a 53 Schwinn (I think), not sure what model though. It has twin straight bars under the top tube. Got it from a guy downtown Chicago. He says his cousin bought an old Hotrod shop in Chicago and the bike was left in there when the previous owners left. I dont know who built it, but I love it! The collector would cringe as the seat has been fabbed and welded to the frame, but the springs still give the seat some bounce. Rides real nice and low. Love to hear any feedback. Thanks, Jay
