cast iron gear case?

[CTaylor]

I just picked up a new cast iron case in preparation for my ppump swap. What did these normally come on? I have never seen another one just the usual aluminum ones

Are you sure that is cast iron ?
It looks like aluminum to me .
I'm toying with the idea of doing a P pump swap on a engine I have .
But the only application that I'd say would have cast iron would be a tractor ,and could be with the red paint , it could be from a Case or International

I'm not sure of the material from the picture but you can check with a magnet easily enough!
