I don't know what A5 means, but the first Campy 135 BCD crank was C-Record in 1985 or 1986. Once the 116 BCD Victory and Triomphe cranks which debuted with C-Record were discontinued, I think all the Campy road cranks (i.e excluding MTB or track) since have been 135. These will take a 39T, 42T is commonly seen on them.

1)Used Nervar 170 right crank arm, 128 BCD rings in 40 and 52. Spindle/threads guaranteed to be good, meaning I never used it but will give you your money back if it proves to be messed up. $50 shipped.
2) Continuing our tour on the more rare bolt-circle diameters, we offer the 118 BCD ring in 42 teeth. A stout ring, used but not very much wear at all. $25 shipped.
3) Nuovo Record rear derailer, Pat. 70, with the front derailer that hung on the bike with it, Pat. in the neighborhood of 70. , $75 shipped and pictures are available.
Info needed: what era is a campy chainring, 135 bcd, 42t, A5?
How does one identify those Simplex delrin derailers? I squint my
middle aged eyes on one here, and see Prestige-Simplex, Made in France
(so far, so good) BrevetG or Brevet6 and S.6.D.6. I also have the FD
and DT shifters (with Campy rubbers), and would appreciate any
estimate of value.
