Thanks for info all. Those tubes holes to show filaments were popular in 1921 to 1922 or 23 maybe years for radio makers. I have had a homemade set, The owner actualy made coil which worked well and was crude. ALL parts on radio are factory made, well laid out and thought of. Very complex setup, cabinet is simple, but factory quality. All wiring done to a certain standard. I have not seen a homebrew set done yet to factory standards.

Unrelated I have recently seen another unmarked radio that seller assumes is a certain make because of audio xfmrs, AND is correct. The tuning caps were made by that maker specifically, One of my first antique radios was this make and is rare.

related is the fact this set has similair type construction and is unmarked too. Some early radios simply were not marked. 1920 to 1921?

I'm just going to realize the generation of collector that knew this set has passed already since set is old. There's only a few old radio collecting books, most have limited pictures for reference.
