Wanted: Identification of artefact

Why three plugs? Probably to connect to the field phone lines differently.

How about we give poor Terry a break of the Bob’s . I thought of posting this in the wireless section but it is wired . So we have two orphans : Terry and ringer . Anyone here know a Jimmy who could help me with this piece of kit ? Then we will have Bobs , a Terry and a Jimmy .

My brother's name is Robert/Robin/Rob/Bob so I can participate as an Honourary Bob...

The US field phone and switchboards had a similar arrangement for the headset plug.

Sounds to me like you missed it by one place on the birth order.

Robert is an old German name that means “bright fame.” It's taken from the old German name Hrodebert. The name is made up of two elements: “Hrod” which means fame and “Beraht” which means bright. The name was introduced to the people of England by the Normans in the middle ages.

Headphone jack.

Thanks Tony , Chris & Jesse . We have collectively determined it’s a Lineman’s tool called a ringer . It is basicly a magneto to produce current . I introduced two wires in the side holes and turned the crank . Ouch ! I was shocked . That’s what gave me the idea of using the volmeter . 4-5 Volts . I will try a few different plugs next week as Jesse suggests it may be a common plug from another piece of kit like a standard or a phone . So the ringer rings the bell on a field phone connected down the line to find and correct a fault . What other application could this be used for ? This is just my two Bob’s but we have at least 4 .
