I bought a front and rear axle at a swap meet, that I was told came from a Marmon Roosevelt. They are pretty complete except for the rear cover. They have brakes on all four wheels, and the wire wheel hubs and caps are there. The caps have a logo on them that looks like a shield, a little wider at the top than at the bottom, and an R in the shield. Can anyone positively identify these as Roosevelt? If so, what wheels fit? And what else used the same wheels? What size would they be? Thank you.
