I have asked before but does anyone know the make of early 50's French components stamped "W" or "TWF" where the T and the F are integral with the first and last part of the W. On the cranks the W has wings. The Dutch Pestmann I am cleaning up has a headset, BB and cranks of this make. There is a lot of weight relieving machining, undercuts etc, the cranks have triangular arms which are milled in the back, axle is hollow etc.
