I am not looking at one, but if it is truly 1/4" wide, then:

Woodruff Key #15

1/4 x 1

it is a standard machinery part

Sure! Just happy to have my 1920 Parts and Price list handy, the early ones have a lot of part dimensions shown. ;)

That key is shaped like a half circle. I think it's called a Woodruff Key. What I did was to take the pitman arm to an auto parts store and got a key which fits in the slot in the arm. It seemed to fit right into the shaft and works just fine.
