Bottechia also marketed a Chorus equipped Cromor frame in the late 1980s. It was called - wait for it - Bottechia Cromor Chorus. This seemed to trend at the time, naming the model based on the tubeset and groups.

The group could also be Victory or Triomphe, as stated by K89, so pics would aid in identifying the group. Bottechia won World's Championship in 1985, 1986 and 1989, so knowing the most most recent World Championship date on the decal would aid in dating the frame.
