Nishiki Rally
I've had this Nishiki Rally for a couple of years now, and I really enjoy the ride (that may be because I have nothing to compare against, other than a couple of cheap department store MTBs).
Going by the serial number, CB 07104, this should be the 7104th frame in 1982. It's got Suntour stem shifters (which I would love to change to brifters, if even possible). The derailleurs are Suntour Sprit in front and Honor in the rear. The brakes are all Diacompe. I have no info on what categories everything fits into... The bike is good enough for me and hopefully my morning commute. I still would love to do indexed shifters though...
