There are two different guitars, both referred to as RR7. One was intended for export (the "US type") and one for domestic sale (the "Japanese type"). Both models, obviously, were produced in Japan.
The for-sale-in-Japan (Japanese) model differs in that it has a regular (instead of mini) switch, like a Strat's. Also, it has an additional single coil pickup at the neck.
The difference with the RR6 is that the RR7 models both have tremolos, and 648 mm scale lengths.
'RR', incidentally, stands for 'Rock and Roll'.

First documented month of manufacture: October 1990 (serial number J90313, see guitar below). Last documented month of manufacture: October 1990 (serial number J90407, not pictured on this site).
