I've added some notes in the archive as Joe suggested.
The coils in transistor radios are for the IFTs and oscillator, generally for an I.F. of 455 KHz or thereabouts, so it's questionable whether or not the cores would work at higher frequencies. (Up to 16 MHz for range 4). Probably OK for the lowest range - 350 - 600 kHz. I guess that's the range of most interest for re-aligning IFTs.
Certainly before anyone embarks on building it, the coil obstacle needs to be overcome.
