[Milsurplus] Mackay nameplated Hammarlund receiver ?

[Paul Thekan]

Miles...
Thanks for the info on  your modified
SP-600 by Northern Radio.
Thanks for confirming what I thought was a conversion to be used with a
teleprinter.
I can find little or no info on Mackay radios.
Have a older Mackay Radio I believe to be from the early 30's and can find
nothing on it.
