[Boatanchors] Who made small mobile receivers?

[Ian Wilson]

I'm trying to identify part of a small mobile(?) rig.
5 bands, 75 through 10m. Only controls on the part that I have
are tuning, antenna trim, and band select.

There are 1750kc and 200kc xtals.

Tube lineup: 12AT7, 6CB6, 6BE6, 6AK6, 3 missing.
Compact (4x5x6" approx). Commercially made (but some mods
have been made).

It doesn't appear to be Elmac or Gonset. Other mobile suggestions?

Thanks for any suggestions.
