I have a mint in box C-91 which is the matching top of the line Elite Preamplifier. It's partner is the M-91 and I have been looking for one to match my preamp for years. The last working one went for $1200-1300 on E-Bay. The M-90 (which is this one) is one step below. Looks very similar tho.

This is one of the things I missed about being in the military. Equipment like this was an everyday occurrence. I would challenge anyone to a well schooled GI from the 70's or 80's who kept their gear. Awsome stuff.
