Re: Dating an older lady
1967 Schwinn would have the serial # on the left rear axle bracket
Second digit of the # would be C for 1967
Kick stand would be welded on
If it's any kind of Schwinn it will be pre-1948 or non-Chicago made post-1982
Try sanding down the repaint to the original paint too get an idea of the paint scheme. Appearance of a Schwinn helps ID model and the era it's from.
