notes: label: Description (Brief)
content: Bunnell telegraph key used by Hiram P. Maxim. "HPM" written on bottom of base. Pole switch is missing. This landline telegraph key was probably not used to operate Maxim's famous "Old Betsey" spark transmitter since the contacts are not optimized for the high currents associated with such transmitters. However, according to KD4KL the key would be suitable for use with vacuum tube transmitters.
