Hi Folks:
   Stronglight offered a 49A(for Acier)crank that closely resembled the 49D(Dural)during the fifties and sixties.Most I have seen were on Rochet touring bikes.
   In Canada,starting in the thirties,CCM did a really cool steel cotterless on the real track bikes that has a triangular taper instead of square.
   Finally,back in the 1890's,beautiful steel cranks were everywhere,some with secret puzzle crank assembly tricks.Very cunning.See Columbia Model 40 of 1895.And while we're at it,Racycle and D&J Patent.
