Tow Hooks: Post your foundry casting marks

[DeadheadNM]

I'd like to see detailed examples of the foundry casting marks present on tow hooks for 67-72 trucks. Curious what's out there. These marks can serve as supportive evidence of an OEM part in the absence of part numbers, such as the case with some (most?) 72-only tow hooks. Perhaps for this style one foundry included part numbers but another did not.

Here's a borrowed example that shows what I'm after adjacent to the part number but it lacks detail enough to really identify the mark.
