It looks like a Profil CX to me. Here is the link to my own Profil CX, also on Wooljersey:
Aside from the finish, the only major difference from a Colnago Mexico of the same (1983) era seems to be the fork. The original finish is, I think what is referred to as "Chromovelato", which looks like candy paint applied over chrome. I have seen several other Profil CX models, and everyone I have seen is the red color. However, there seem to be variations in how much chrome on the rear triangle is exposed. Also, I have seen one or two with the shifter mounting boss like that of an Oval CX, where the shifters are mounted above the top tube rather than on either side.
