    In the telegraph world, they were known as a "polechanger". Here are pics of my Western Union polechanger key, which was made by Bunnell. Yeah, it's dirty; I haven't gotten around to restoring it yet.

    That's actually a fairly oddball polechanger. Most of them are as shown in the photo (below) which includes the common Spies and the less common Bunnell. I think Western Electric also made them. They were used with a wheatstone bridge to try to find the fault in a downed telegraph line.

    The stapler next to the keys was a cheap Japanese novelty item made late 1960's DSCF0149.JPG

    These are 20th century devices. See photo from a Bunnell 1928 catalog. Polechanger cat. 1928.jpeg

    Thanks all for the photos, comments and detailed information... I agree this must be a pole changer... MESCO must not have made very many of these as I can't seem to find any details or photos of MESCO pol changers. Anyway I'll just add it to the collection for now.

    So this is why I can't find my stapler. They're evolving camouflage!
