Here is a link to your bike:

This is the bike I came across two weeks ago and has kept me busy in my workshop virtually every night since. 18 speed. Rides nicely, but I cannot deal with the downtube shifters, so I am converting to bar ends.

Fuji put out a lot of bikes with seemingly minor changes to differentiate some of them. For instance, in the same 'deal', I also got a Fuji Berkeley, which specs out almost identical to your Monterey (exception being crank metal).
