Looks like it would be very nice after a full restoration. Serial number suggests a date of November 1951. I really do like the fancy decals on this bike... wonder if there are replacement reproductions available? The clip for a pulley on the top tube near the seat post indicates it would have had a 3-speed hub and a shifter on another clamp a few inches from the head tube. Would have also had chromed steel fenders and steel sidepull hand brakes.
Must have been mighty pretty in its day. Probably weighed 40-50 pounds, but think what a smooth ride it would have had.
I'm pretty ignorant about Schwinns. But I'm curious - if this was the model right below the Paramount as the seller claims... then what had happened to the "Superior" during these years?
