I picked up this Schwinn single top bar Sunday and have been wondering what it may be. It's post war, based on the drop outs and built in kick stand. I'm guessing it's pre '48 due to the serial # being on the bottom of the crank tube and not on the Schwinn serial # lists I've seen on the internet (starts with a J). I haven't taken out the crank yet to look for a date code. The Morrow hub on it is dated April 1945 ( O 4 ). It is painted a very dull and old gray and appears like it never had a head badge. Looks to have a Huffman style stem. Not sure if all parts are original but it has been in this configuration for a very long time. Grips for sure and possibly bars are parts that seem newer.
