Thanks bonneyman, this wrench is awesome. I'm guessing it is late production due to features and 5 digit part number. No triangles anywhere, Cooper production? I don't even know when they stopped using the name.
I kept the ebay luck going with a Bonney ALH36 deep 1-1/8" 6 pt. chrome 1/2 drive socket I just won for $1.62. This one has a Triangle so easy to tell when it's from.
The V-gullet and Loc-Rite box broaching make it a Triangle Tools era wrench after 1967. Cooper was later in the game (approx 1990). Long combo wrenches were made in both full polish and satin finish up to a 1 1/4" - above that they were only made in satin.
Only the sockets and drive accessories have a little triangle under the "Y" in Bonney IIRC.
