I have had this Roadmaster for a while... Assuming its a 51' but I figured I would put it up here and find out because it seems a bit older...
Serial # J90192 then the normal C with the lil' "w" in it If any one can shed some light on the year that would be great!
I have what I believe to be a Roadmaster or a Hawthorne with serial no. J 58288 CW. It's my dad's I believe. It's similar to yours, with curved fender braces, same chain ring, except no springer front fork. The head badge is long gone, fenders are peaked. I remember seeing a torpedo light somewhere around the garage that went with this bike. I'm trying to ID mine, too, if anyone has ideas.
One interesting detail on mine is that the dropout adjustment bolts are slot heads not hex like most CWC bikes seem to have. Anyone know what this bike might be?
Thanks in advance!
