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.
