I have some bits that may be of interest, pat 83 Super Record front and rear derailleur's, matching crank with 53 42 rings (inner campag outer Royce) and Royce crank bolts, plus Simplex retrofriction shifters with cables, all currently on a bike so known to be in perfect working order.
I also have a pair of Mavic Open 4 CD's on Campagnolo Veloce hubs and a 7 speed cassette 14-24 which works very well with the above.
