This 1 3/32" socket has been permanently attached to this short 1/2" square rod (probably part of an extension) and then the top has been stepped to accept 1/4, 3/8 and 1/2 inch push through old type ratchets.  They made a good job of it, but why??

Dunno why

but maybe open end wrenches too?

You could use it with all 3 ratchet sizes??

those look a lot like the square step-ups on the old faucet seat tool (other end usually hex).   strange

this begs a question:

female ratchets in all 3 sizes?

other than refrigeration tools I have no 1/4 female

anyone else?

Skip

There are marks on the step up that indicate it was made with files.
