I think I just picked up the same bike - rescued it at the curb on trash pickup day. The one that I have appears to be all original so maybe these photos will help. Rear hub is a SA 3-speed dated Sept 1958. That's the only way that I have of assigning a year to the bike - couldn't find any serial numbers any where. 40-spoke rear wheel. Just started to clean it up. I'm also in PA if you want to come look at it.
