CR, to aid in dating a French bike by its various components,

does anyone know when Nervar three pin steel cottered cranks first appeared?

I searched the CR Archives and found nothing on this. Thanks, Peter ...................................... Peter Brueggeman La Jolla California USA pbrueggeman(AT)ucsd.edu
