It does have a molded star in the faceplate so I guess that's what it
must be.

Interestingly, the IC1 on this drive is a QFP chip from Hitachi (HA16642M=
P).
The PC board revision is "Rev. C" so maybe that's part of it. I think thi=
s
is probably an AT-era drive but I thought the base AT came with 1.2mb
drives? Maybe an option?
Does it have a '*' moulded into the front panel? There was a 360K floppy
drive option for the PC/AT, and it was distiguished from the 1.2M byte
versiobn by having said '*'. A crazy idea, since older 360K drives were
not so marked, so it would have been clearer if the new type of drive --
the 1.2M one -- had had the marking.
Anyway, if so, I should have some info on it in the PC/AT
options/adapters docs.
