Sam,
I'll send you a picture of one wheel I have at home. Looks very similar to what you posted here. It's a peaked spoke like an American Torq Thrust, but has a steel rim. If I'm not confusing it with another of the wheels I have in the pile, I believe there's a "K" on the back indicating it's a Keystone.
I ran a set of Keystone steel rim/Aluminum face wheels on a '65 Impala I had but honestly don't recall them having the peak on the spokes. Too many years have passed!
