I'm not sure about this, but I think it was around '96 or so that they went to the high wire concave, long shoe, and wide space rasps on the cyl. bars. Increase in power too, I believe. If I were in the market for a Series II era machine, I'd try my best to find one that year or later if I could afford it. The high wire concave also had the wires spaced further apart and does not require removing every other wire. We had a '93 R52 that we removed every other wire and the holes were almost TOO big - let a lot of cob through onto the shoe, but sure made a big difference in rotor loss.
