WTB Power Cord for Gonsett Xmtr

[David Jennings]

I am looking for an AC power cord for a Gonset G-77 transmitter.  The male
mating plug on the transmitter looks exactly like the ones used in tube type
TV sets from the 50s and 60s as a safety interlock.  I used to have a
"cheater" cord for working on TVs with the back removed, but it has long
since vanished.

Any extras or possible sources are appreciated.
Thanks
