Original bumper identification '67-'68

[Jonk67]

Hi all, is there a stamping anywhere in particular on '67-'68 bumpers to identify them? I'd like to look for a pair on fleabay, CL, etc. but want to make sure they're original ford. Where did they stamp and should it be a standard C7, etc. part#? front/rear
I'm looking at a rear one online but the only numbers are near the license plate indent and say '9 14 2'.
thanks, Jon

IIRC, there werent any part numbers stamped, but were painted on when new. the letter stamping process would have created a blemish in the metal on the outside that would have needed to be addressed before chromework.

Those numbers are on the inside portion TMK. I am guessing the inside would be ~bare or painted with some type of sealer/primer as the one I'm looking at appears. . I have repops and they have a thin coat of the chrome on the inside.
Here's some pics if anyone can determine if it's original.

Think it's worth $50-$75 shipped to get straightened and rechromed?
