Here's a beautiful set of top of the line Shimano Dura Ace  road pedals from the mid 1980s.  The model PD-7400.    These came from a display bike with no actual miles.  Any marks are from moving around/storage.  These pedals are  complete with the Shimano  pedals and Clips with Christophe Straps.    

I see these PD-7400 pedals with black backs--these are the same polished aluminum as the rest of the pedal and may be the first version released in 1985.

Check out the pictures and contact me with questions.
