[Milsurplus] Carrier Monitor Info Please

[Chris Kepus]

Mucking around in the corners of the stash, I came across one of brand
spanking new Carrier Monitors I purchased from Fair Radio.  This little guy
was just too cute to resist....and is still a beauty, IMHO.  Fair was
selling them for a song and a lot of us bought them for the Jennings
"Peanut" vacuum cap that was packed with the unit. My original plan was to
part it out but, after getting my hands on one, I've never been able to
convince myself to part it out.  Now, I'm thinking I can use it to monitor
my AM signal.   

Anyone have a schematic or TM for this unit:  Here's what's on the tag:

Carrier Monitor
Stock No. [not stamped]
Serial No. 822
Hallamore Mfg. Co.
Long Beach, Calif.
Part No. H.M.C. 1028001
Contract No. AF33(600)21727

I've looked the unit over, inside and out, and don't see any additional ID
information. If anyone wants to take a look at this unit, copy this into

Thanks in advance for any info.
