Very interesting frame !
Built in December 1993 for the 1994 season, probably for a profi team ( not sure which one ).
U.Scanini is a Belgian brand (frames imported from Italy), Eric Vanderaerden (prominent cyclist) used their frames and as a result his name was next to the name of the "manufacturer".
Since U.Scanini "rebranded" the frames, EMC's Mx Leaders may also have gone to him.
In 1998 Team Collstrop used E.Vanderaerden there (in 1996,1999 and 2000 he used EMC frames).
To check is who used U.Scanini/E.Vanderaerden frames between 1994 and 2000 and a piece of paper (if it survived) on the fork steering tube.
