Nick, first, thanks for all the great hi-res photos. I am not sure when the 6AU4 was introduced, but this set may perdate its introduction. I have production 15" color sets with 1B3s in them, so it is not unheard of. Probably hard on the poor 1B3s, but they work.

You are probably planning to do this, but I suggest you make a tube chart, listing tupe type/mfg/date code. Also, a list of part numbers on all transformers, as these often contain date codes and manufacturer info.

It is anybody's guess if the CRT is still under adequate vacuum to operate, but the signs are encouraging. Of course, my Hawkeye rebuilt 15GP22 tests good, had beautiful getters, and lights up purple like a neon tube when voltages are applied! So you just can't tell by looking.

Do you have the missing tubes, or are these going to be part of the mystery? I don't see tube numbers marked anywhere.

Are any of the control labels readable? I can't tell from the photos.

This a a fantastic set, thanks for sharing. I look forward to your upcoming discoveries.
