Nye said that the "Master Key" was "the first major improvement in telegraph key design in 50 years," and was "designed for the expert... perfect for the beginner!"
The main feature of the Master Key is a contact assembly that is isolated to keep the keying circuit separated from the base, the key arm assembly and all exterior metal parts. This, the ad said, would greatly reduce shock hazard.
Has a heavy die-cast body. Contacts are gold-plated silver. Adjustable action key arm has Navy knob.
