Campy Nuovo Record 52 Pat no pin ring well used

A Campy NR 52 144 bolt circle road ring.  Fairly well used but you could squeeze a bit more out of it if you like doing such things (we've seen much much worse used).  What is nice is that it has the patent marking and no pin.  So for finishing off an early 70's restoration that needs this ring, here is an affordable option.
