More mystery stampings... 59/60 PX10.
What is the serial number on your BB? ..and do you have any other stampings on top of your bottom bracket shell - like RGF. ? I have a '59/'60 model with similar lug work, and that came with a riveted on head badge as above, and has similar cryptic letters. Yours has different front forks though, but they may have been switched. Hmmm, there may be something slightly different about the dropouts as well... I would have to look closer at mine.
Thanks for the comment. I'm pretty sure that the forks are original, as they're very similar to a '74 PX10 I also have (too small, sadly..).
I see that you also have the mystery RE stampings!
Here's the BB underside, showing the stampings (nothing is visible on the upper side):
As clear as I can get, but not bad, given the age of the frame.
