Original Towers Plaque?

 

I found this plaque recently and it was claimed to be one of the orignials. Obviously not cast, perhaps either a one-off that someone created in the machine shop, or maybe one of the original designs?

What's interesting is the insertion of an eagle on top of the "9", not present in either the patches or other Towers plaques I've seen. If anyone has any ideas as to the origin of this plaque, please contact me.

Thanks!
