Great thread...Thanks! This has helped me to identify my "mystery Hoffman" that has been left un-restored for too many years in my garage.
Time has not been so kind to my set, however

... Picture1
It is missing one knob and the Ch selector knob is broken... Picture2
Big "ouch!" on the cabinet...Picture3
Chassis is missing one tube, but seems more or less complete... Picture4
Anybody know what the missing tube behind the tuner might be? ... there was no layout chart or model number on my set (back was missing). Stamps on chassis say
"B013380, Feb 21 1950, Chassis 155"
Good luck with yours, I will be following along for inspiration to begin work on mine.
