Yup , pretty sure it's a 1937,(36 has a different seat post nut and the 38 (and above) have drop stand ears. I love these frames and have two, unfortunately (or fortunately for me) they usually don't go for much. I have a Hawthorne and Zenith but these are also badged as Rollfast. They do however make great riders and look great - they remind me of the pre 57 Harley hard tail frames. Buying the tank, guard, rack and fenders are where the price goes up. I've seen tanks go for as much as $400.00 but have purchased two for much less each ($250). Chain guard, $60 - $80ish and about the same for the carrier. I do love these frames but what do I know, I just buy what I like and enjoy them!
If anyone knows more, Please feel free to correct me!
