Hot Rods Can anybody ID these slot wheels?

Can any body ID these slot mags? They are 15x8.5 and measure 3.75" back spacing.
They have a sicker on the side that says m&w inc.

 

Aluminum. Next.

 

Rocket wheels I think. Had a set similar

 

Pretty nice old wheels. I think they will polish up nicely.

 

When I bought them they had a set of old 27.5x11x15 bfg road race type slicks on them. Never seen a set of them.

 

I think they are Ansen Sprints. 1970s

 

Blue Line racing made the same wheel in the 70's

 

The lug nut holes are oval with a slight internal taper ? International Mags that were in Benicia,CA had a contract with Mongomery Wards back in the early 70's m&w ?

 

Yes, the holes are oval with a slight taper.
