Well the RS11 with no suffix is just the controller but since yours has a
motor and a "W" serial number it sounds like one of the fixed head disks
for the RF11. I'm guessing that the tube would connect to the air
filtration system. I've not had much luck locating a picture for
comparison. I'll bet you any amount of money if you were to open it you
would find a single platter attached to that motor inside the housing and a
pair of read/write heads.

I can not see how a suffix is missing, since the label
is without
marks other than those used to emboss the "RS11" identification.
As for this being a hard disk assembly, please tell me more.
One other item of identification is that the gold top cover has a
pipe sticking out of it, which is curved and of diameter about 1.5",
and to tell you the truth, I thought this paperweight was some kind
of blower or air conditioning unit. Still, the weight of the unit lends
credence to the notion of it being some kind of DASD (to use IBM
parlance).

This is where the Option/Module guide comes in
handy.
RS11 - probably a suffix missing (either B,C, or D and an optional
A)
This is a HDA (hard disk assembly) for an RF11
drive which could have two
such
drives installed.
A complete RF11 consists of
RF11 + RSO8-M + RS09-M (yours is the RS09-M)
