That only narrows it down from 1953-1963. If the RD has a cable adjustment screw, which we can't see from the pics, it would narrow it down to 53-59.

But the skewers are open C. That puts it 53-57.

The lock nut date code can probably narrow it down a bit more.

The problem comes with the shift levers, closed C. 1960 and beyond.

Clearly a mixture of parts added who knows when. But can easily say 50s/early 60s.

The Scheeren rims are probably wood filled and really, really cool. As is the Titan stem with the Maes bars.

Definitely setup for racing.
