WANTED : Bathroom Sliding Mirror Knob

[IOLANI]

Hi folks. I'm missing one of the square acrylic knobs on the sliding mirror in the V Bunk head. It's the same knob used in all 3 bathrooms so I'm assuming they are original from Hatteras. I see some on Amazon but none exactly the same.
I know it's a longshot but does anybody have one they removed or don't need ?

I’ve been aboard lots and lots of Hatteras is in this is the first time I’ve ever seen a mirror pull like that. I’m probably wrong, but I bet it was an add-on from a prior owner.

I've seen those before. I think they were late 80's that had those. Saw a 60MY with them.

Thanks. My boats an '86 MY so maybe original. The mirror pull that Sam's shows is completely different.
I'll check the one you suggested on Amazon. When I first glanced at those photos online the beveled edges looked like they were fluted rather than smooth but that may just be the photo.
