FWIW, four years ago I posted this document which shows coil and major capacitor frequency ranges and part (drawing) numbers for all variants of "command set" units:

The tables in the above document need a correction: The frequency range of the 1958 A.R.C. Type 12 receiver R-22 is 0.55 to 1.6 MHz, not the .52 to 1.5 MHz range of all earlier broadcast band receivers.
