YUP, that's it.  Mine are black, ordered by Western Electric to write 
call logging
data from ESS switching systems.  These drives will power down the 
vacuum/air
bearing pump when inactive for a while, so handle very intermittent 
writing well.

I can't tell for sure if that is a 92181 (800/1600 BPI) or a 92185 
(1600/6250 BPI)
but it looks so much like mine I think it probably is a 92185.  Probably one
of the finest streaming tape drives made.  I've seen a lot of bad ones, too.
We had a Cipher 990 that never worked well, and consumed $80 read
channel chips every couple months.  We had a $10,000 DEC (Pertec
T1000) drive that melted tapes onto the head.  (That wasn't  streamer
but a vacuum column drive.)  The fact that this CDC drive powered up
and ran after sitting for 15 years or so is pretty amazing right there.

It will run in start/stop mode at 25 IPS, streaming at 25 IPS or streaming
at 75 IPS, and selects from those modes based on the data flow to/from
the computer.

I was the DECUS (Digital Equipment Corporation User's Society)
tape librarian for the local user's group for a while, and it was a great
boon to pick up 3 of these drives from a surplus outfit for pennies.

But, even my primary drive has probably run less than 200 tapes on
it, and the drives were new when I got them.
