Help me ID this bumper

Guy had a listing for a '58 Pontiac bumper, but this is the photo he sent me. I don't know what it is, but I know it's not a '58 Pontiac.

Anyone recognize it?

 

1950 cadillac rear?

 

Wow, that was quick. And pretty darn close if you ask me. (I wondered how that license plate light would work facing UP!) Thanks, I'll p*** on the info. I don't think he wants much for it.

 

Looks like my 51 rear bumper. I think 1951-1953 Caddy...

 

Yes, its a 50 cadillac rear bumper
