I picked up this lineman splicing clamp Sunday. I tried fruitlessly to find a youtube video demonstrating how it was used. I assume it just holds two wires parallel while you twist the ends around, but IDK.

The other thing that tipped me toward buying it was that it doesn’t say M.Klein & Sons, but just M.Klein & Son. AA shows an 1898 advertisement with the same name, but erroneously captions it M.Kein & Sons. I don’t see a mention in the company history on AA nor on the Klein site that gives a date when a second son joined the firm.
I suppose “W.E.Co” is Western Electric.
