The name was changed to Signal Electric Manufacturing Company and they remained in business until the 1960s when they were purchased by a Thermos company. These were available with different size contacts depending on the intended service.

The hand key shown below to the left is a Signal Electric Mfg. This key has 3/8" contacts for medium duty spark gap transmitter applications.

These keys were normally supplied with the Navy "Finger Rest" type of knob as shown on this example.

The SE68A keys were later sold as surplus to hams and are advertised in the back section of the 1937 ARRL Handbook (for $7.50.) J. Bunnell & Company was formed in 1878 by Jesse Bunnell, who had a long history (even at that time) in the telegraph world.

Simple to operate and virtually incapable of making errors, the Hand Key is the basic tool for the radio telegrapher.

The J-6 was used by the Signal Corps for the small airborne spark transmitters that were in use at the end of WWI up into the early 1920s.

There were various owners after Jesse Bunnell's death but the company did continue on with other owners.
