HP (3rd party) id help?

[Rick Bensene]

I think that this is a Racal-Vadic 1600-series modem bank.
It was a rackmount unit that had slots for up to 16 (typically Bell 202)
modems.
See:  http://www.arcelect.com/racal_vadic_202t_202s_modem.htm
You will have to scroll down about 2/3rds from the top of the page to
see.
The photo shows units that are very similar if not identical to what is
shown in your photo.
