Your e-mail prompted me to reach about five feet, open a plastic storage 
container and voila !!! there-in resides a Heathkit hybrid phone patch Model 
HD-15  (must be hi-definition) .  Traditional Heathkit green with gray top 
and sides.  Worked many years at one of our flame-throwers.  Still would 
work for me but phone-patching is pretty much history on ham radio.
