Can anyone identify this set?

Airmaster? I've seen that brand on another set before. That cabinet looks like un-laminated particle board!

Channel Master?

In the 50s, Tech Master sold TVs for custom installation, but I think these were mostly 630 clones with various sizes of CRTs available... perhaps a long shot that they might have used other designs :scratch2:
