What rear bumper is this?

[Patch]

Hello all. I do realize that this was most likely an aftermarket bumper my Dad put on this 72 after he purchased it new, but is there an actual model type...or are these even offered by anyone any longer? Thanks in advance....
P.S.-Found a different photo that actually shows a different earlier bumper. The earlier one didn't have the hitch mounted to it and although it doesn't show up well, it's got a placard that's red/silver/blue that almost looks like a Holley tag. huh...
