Need help identifying some Wheels

[Tobey]

These wheels came on a car I recently bought. Two of them had Cragar SS center caps; the others had no caps. Stamped onto the rim is "7Lx15 CMW 74 3 Rim Made in Japan".
On the inside of the spokes, it says "Meets SEMA Specs 5-1", "Patent Pending", and a load rating.

Edit to add that the spokes are painted, but appear to be aluminum where the paint is flaked off. The rim is steel.

Are these a Cragar wheel made in 1974?

Thanks for any help with identifying them.
