OK, it's a 1984 model. The main tubes are plain gauge CrMo, the stays and forks are probably hi-tensile. You don't provide the models of the components but I know from the 1984 specs what they are and I used to ride a Norco Sasquatch from the same period, so I'm pretty familiar with the bicycle. Basically, it's a low mid-range ATB for the era and it's one of the old school designs, with real long wheelbase and lots of clearance. A nice enough bicycle in its day but nothing special and quite outdated by to-day's standards. FYI, original cost $299 US.
