The Walden Worcester wrenchs are a mixed bag. Haven't cleaned or IDed any of them. Also got a flat of similar but not Walden Worcester wrenchs at same auction. One was a Mossberg 320 that I didn't have. Also got this unmarked socket-flat end that I want to call a Ford wrench but don't know much about old auto wrenchs. Am I wrong?
I do not know this wrenches specific application but I believe you will find that this tang end was used to release the lever found on what was refereed to as a split rim back in the old days.
Teens on up until approx 1931 or 32 ( if memory serves ) me Dodge Brothers cars/Graham Brothers trucks used this sort/a variant of this tool and was part of the original tool-kit.
Often mistaken for a gadget to remove tires and while I am sure it did come in handy for that purpose that was not its intended design.
I am not sayin that this was this tools specific purpose because again I cannot identify the wrench enough to put it in with a specific manufacturer of automobile assuming it was built for a specific tool-kit.
I am jealous of that pile of wrenches.
