If I hazard a guess I would say your 62-101 Airline probably was made by USR&T. Check out the USR&T chassis 1009, model 3070. It is identical to the 62-101 except is uses 46 tetrode tubes instead of the 45 triodes. The chassis layout and design appears to identical. Even the way the schematic is drawn and laid out is very similar. It is known that USRT made a lot of Airline radios. I know that USR&T did use Utah speakers as I restored a 1930 TRF USRT model 29 set that had an original 10" Utah electrodynamic. I hear that Utah speakers were made in Huntington, In. which is only a few miles up the road from Marion, In. where USR&T was located. Also, USRT did mark the tube #'s on their sockets.
USR&T & Grigsby-Grunow combined into General Household Utilities sometime in late '33'.
After all this time I thought Utah was located in Salt Lake City only to find out they were only 20 miles south of where I grew up as a kid!
Small world hey!
