Stronglight 49D with 32-52 and 14-28 5s on the back. The rings were completely flat and with full profile teeth, as befits a crankset introduced in 1949 (the steel 49A was ten years older but otherwise the same). Campy Record/Rally derailleurs. Wasn't the smoothest upshift but was never a problem as long as you weren't late. The FD broke at the clamp after 11 or 12 years, the RD had already been replaced with IIRC Suntour ARX GT when its cage spring broke.
At some point before the FD broke I'd switched to a Stronglight 99 with 32-44 and 13-32 7s on the back, I don't recall what the replacement FD was.
