Hot Rods '32 Roadster Starter Relay Question

I am building my (12 volt) 1932 Roadster.
I have a 3 post starter relay in the system.
(I think the style relay lived in an early 60's Ford)

Battery Cable onto one side of the relay...from the Battery itself.
Other side of relay travels down to starter motor and feeds the wiring harness.
(Third post operates the push button for the starter)

Question is...
Does this relay

 

Maybe.

3 post is a 6volt, I believe.
