1967-69 Barracuda bumpers

I don't see any stampings or part numbers on these. I will check closer later today. Not sure if they marked bumpers or not? I got these in a parts lot I purchased from a guy who sold a car before he installed these. He has had these in storage for ten years. You can see that they were installed before the re-chrome process by indents at the bolt holes in the back of the bumpers.
Mabey someone will chime in on bumper markings. I do not think the gentleman had any reason to be untruthful or mis represent the fact that these were originals he sent out for re-chrome.
I welcome any additional info someone can share.
Thanks.
