Thoughts on this Sub Insert

[Gmt21]

I bought this some years ago on Ebay. I'm thinking it's from a 16800?

It has a nice gun metal fade and mostly normal-looking wear to me, and nice pip. The back is black, the lighter colors there are gunk.

There is some odd-looking texture wear around the number 20

Any thoughts or concerns?

Frank, precisely as in my 16800 #8.275.XXX.

Very nice patina, how's the pip glowing under UV?

Thanks,
The pip gets activated by UV but dies immediately after light turns off so I believe it to be original tritium.

That's perfect Frank, on which Sub will you instal it?
