Leatherface Pt3 Help...screen-Used?

[🪦 kaizu13 ●]

There was guy selling off all his stuff on auction where I live.
I came across this mask.



The seller purchased this ten years ago at a junk shop for movie collectors.
I know this "shop", alot of rare stuff tend to pop up here occasionally.
He was told it was a screen-used from TCM3.
The description states, very old, has a few tears and is signed by the actor.
I've seen fakes stating "screen-used" on e-bay and it doesn't resemble the one I've seen in the past. I do not know of any screen used TCM3 masks of existence nor do I know how many were actually made for the film. I do know that the one in the excalibur teaser trailer is a different mask from the hero seen on film.
Is this some kind of replica? Stunt mask?
Keep in mind the ear flap is folded inward in order to show a signature in the 1st and 3rd pic.
Thanks
