Long single side box end wrenches
« on: November 08, 2021, 12:43:29 PM »
Just picked these up because the price was too good to ignore. Only one has a makers name, it's OTC 653. I tried looking through OTC catalogs and got nowhere. The others just have part numbers, 24509-B, 24513-B, 24519-B, 54890-B, and 54810-B. The longest is just over 21 inches in length.

To me they look like diesel tools, big rig or marine, but that's a guess. Any ideas?
Rogue River, OR.

I believe they are aviation wrenches, probably for use on radial engines.

The third one down looks like one of the OTC Allis-Chalmers tractor special wrenches in the 49-J catalog on page 28.
