Serial number R52377. Trying to figure this out all by myself. So there may be mistakes. Prewar stuff is tough. But using some of the guidelines in the serial number search I'm putting this at 38??? Then I pulled out my new book any may have found the model. D97x could be completely wrong but we will see. The fork has some minor touch up. But the frame was completely stripped and I did my best paint job that I could possibly do. Not perfect by any means. But looks a lot better than it did when I picked it up. Asking 600 shipped or best offer. Any questions please ask.
