L D9551 - Mx Leader had a "century geo", check the tables on BigSourcEMerCkx; the frame is from the same period as profi frames, but they didn't build "profi only" frames back then - anything is possible (I don't know of teams using this paint scheme)
A D3586 - built late summer 1992; "EMC worker" A markings also appear after "B3000", updated information in BigSourcEMerCkx
