These Dura Ace cranks came off a bike from the early to mid 70's. The two letter code on the inside of the arm is "RS" (if that helps). They look exactly like the cranks from the '73 catalog on Sheldon's site.
170mm
Chairings included. Everything is in great condition with minimal wear on cranks from strap rub and minimal chainwear on teeth.
$125 (shipped) . Would also consider trading for a Huret Jubilee or Simplex derailleur set.
