[TMC] GPT-750 origin

Hi Michael,

That's great, but not entirely unsurprising!

Which variant of the GPT-750 do you have?

I have a GPT-750C-2, which is the SSB/DSB/ISB/CW variant; it is one of 
the more popular versions of the the GPT-750 series, alongside the RTTY 
version. The plate-modulated AM version came in third, and the CW-only 
variant was the least popular of all of the GPT-750-series units built. 
My GPT-750C-2 was manufactured by TMC in 1963.
