I found the OEM manual on bitsavers and it's
actually the 'R' model
that matches what I believed to the industry form-factor of 8.5"

since I've never seen another 8" drive that size.
Ah, that was it. They
made the "R" model narrower to make it easier to
fit them side by side in a rack.
I'm guessing that the 9.5" size might match the size of the genuine IBM
33FD, 43FD, or 53FD drives. Although I have some 53FD drives, I've
never taken them out of the equipment they're installed in, so I haven't
had occasion to measure their dimensions.
