Need some advice

I recently bought a Colnago MTB frame (complete with Colnago branded Canti brakes). I believe it's a 1992 "Superlativ".

Being a roadie, what kit do I go for? The frame is a late 1980s / early 1990s frame (AFAIK, a '92), but I've no idea what ranges were current then. I know Deore / Deore XT goes back that far (Possibly DX/LX?).

Campag is out of the question as Campag MTB stuff in unobtainium unfortunately.

Ideally I'd like something "period" and reasonably top end, but not wanting to spend a fortune for something that's going to get ridden in dirt and water and snow...

Just hit the Archive, it's in there under Shimano and Suntour for the year 1992 and a few around it.

Might be Campag and Mavic as well, but I cannot remember.

1992 for shimano was M900 XTR, M735 Deore XT, M650 Deore DX and M550 Deore LX for the MTB range.
