Marx Auto Transport

I'm posting this Marx Auto Transport I recently acquired with other vehicles in a collection. Pressed steel like the Structo cab/trailer I previously posted. I think the truck is in good shape. Nice tasteful litho, check out that front end. Marx's litho was on par with the other toy greats IMO. Trailer has some paint mars, but I think It's displayable. The ramp almost looks new except for the paint scratches on the tab. To be this old and actually played with it looks good overall. I need some cars to put on it. Would appreciate some advice and info on what would be the proper vehicles. Maybe you experienced folks could help me. I'll try to post the Hubley lowboy set with road grader next.

Thanks for looking,
Bill
