Does anyone recognize this Challenger socket?

[Oida!]

Gents -

I stumbled across this Proto (Challenger) socket while I was browsing through a flea market earlier today.

This little socket cost me a grand total of fifty cents...a deal I just couldn't refuse even though I have little or no use for a socket this big.

This Challenger is a 12 pt socket. There is a three digit number (524) on the left side of the stamping. There is no marking that designates it's size. But it feels like a 1" or 1 1/16 socket.

Could anyone shed light on on this socket?

And, if anyone could use this socket, I would rather it be used than collect dust in my Man Cave.

Cheers!

Oil pressure sending unit socket. Should be 1-3/16"

There are some op sensor sockets that are 1 1/16. I believe that is what you have.

^ be my first guess too. 1-3/16" = oil pressure sending unit socket.
