This is a hard to find, antique linesman's pole hardware wrench marked in raised cast lettering "LC-25-A" on the handle section. The wrench has two sizes at the large opened end, and three sizes at the small end. The sizes is on the small end are .54", .63", and .82", and at the large end is .93" and 1.13" width. The wrench weighs 2 pounds, and is 13" long overall. It was most likely made to fit a specific machine, and most likely for square type nuts or bolt heads due to the deep inset of the slots. The wrench has some dings on it, but is very clean, not rusty, and not cracked. This wrench was used by bell system linemen before the adjustable wrench was considered to be a better alternative. Unique! We did find this one in the Schulz's Wrench book as No. 1036.
