It's a beauty!

The brakes are Weinmann side pull calipers with large block WEINMANN lettering on the arms. The rule of thumb with Weinmann brakes is that the letters got smaller over time. These are earlier than the late 50's.

Nice fork crown! It appears the brake return spring is bent around the arm of the caliper. By the late 50's the end of the spring was straight, and it rested against a little knob forged into the back of the arm. So again, I don't know the exact chronology but these brakes are earlier than the late 50's.

Maybe someone knows enough about Simplex derailleurs to comment on the gearing. Does that derailleur really have only one pulley wheel? If so, it might be a Champion du Monde Extra Leger

I'm currently thinking this bike can be no later than the late 1940's.
