This is such a cool find!! The plug is from an old telephone switchboard. It has the name “Trudy Price” engraved on the side. The chain is an old brass one and has a great little blue rotary dial phone charm on it. The switchboard plug is 2 and half inches long. See photos for details and be sure to scroll through all pictures, not just the first one.
