Hi,
I am searching for an inner (nearest spokes) jockey wheel cage plate for a Campagnolo Record rear derailleur (circa 1969) and listed as spare part no 815.
I will either buy or swap for various other campag Gran Sport rear deraileur "bits n pieces" that I have in my tool box. Try me - I might just have that piece that you are seeking.
