I'll avoid the easy joke about diapers................ Cool pic!

I don't think that's a Ford. The hubcap doesn't have the right shape for the wide five wheels that would have been appropriate for that style grille. That and the closest shaped grille to that would be a '38 standard which wasn't plated below the trim piece. Can't tell for sure, but also looks like there might be a character line stamped in the fender.
