Mid 70s and i think thats a reynolds sticker.
The cranks don't look familiar, but black painted head lugs and clamp on DT shifters suggest nicer. Looks like there are no braze-ons. But rear triangle is not chromed.
Also interesting is the 3color stripes surrounding the downtube logo instead of 5, suggesting an uncommon market.
Its my size and i dont have a yellow bike yet, what do you guys think?
