Note
There was a gap in advertising between 1962 and 1970, after which the units reappeared and were being made by KIrk Electrinocs. It is not known if the units were being made and sold in the interim.
All of these units are just variations on a theme, and all function in the same way.
The MC and HCE models appeared after advertising resumed in 1970.
