I saw 531SL stickers only on 2 EMC frames, the others were standard 531 (fork stickers were not used - except for team frames). Somewhere around 1994 the owner decided to "upgrade" the frame: all the old slides (BB cover and TT) were removed and replaced with new ones (TT and head lug).
Great job!
Many thanks for the great info! Since discovering the forks are Columbus, I have removed the 531SL decals from the forks and will build up with full Campagnolo Nuovo/Super record. Currently awaiting the arrival of frame #F1122 Corsa Extra Team Motorola
