Technical Bumper I.D. Needed

Need some ***istance in figuring what these belong to: Pontiac, Chevy, Oakland, Henway....?

Obviously would have come from a vehicle with a rear mounted spare originally, with the split bumper.

What say you?

 

Here's a 32 Chevy Confederate Coupe rear:
and a 33 Chevy front

 

The rear irons on the Chevy in the pic are a bit different; doesn't necessarily mean the bumpers themselves aren't a match though. Front iron is closer, but I think mine is a one-piece where the one offered for comparison is split.

 

Yeah, looks like it doesn't have the one piece brace bar.

 

Looks to me like it was one piece, but cracked at the bolt hole.

 

Here's a 32 Plymouth roadster with a solid brace bar for joining the rear bumperettes. The brace bar appears to have some bends in it that yours doesn't. Think it's safe to ***ume yours is in the 32' range tho.

 

Interesting. The same, only different! Based on the bolt hole spacing distance to the edge on the rear bumper, I'm leaning towards the Chevy. Even a '31 Pontiac looks to be similar, but different irons.
