[Johnson] Ranger (original) schematic needed

[Don Ehrlich]

I have the original Ranger without the time sequence keying circuit and would like to modify it to add the keyer deck.  Any suggestions would be welcome but I can engineer and build it myself if I can only find a copy of the schematic of the *original* unmodified ranger so that I will know what I am starting with.  I do have the manual for the later Rangers that do have the keyer circuits.
