Strange spots in tube.

[Bigwolf]

NOS(?) tube with two white spots. Both near the getter area.

The first white spot is around a dark points on the metal construction of tube, you may see one point on the photos 1 and 2.
The dark points are close by, and big white spot on glass is the result of the merging of both areas.

The second white spot is exactly on the opposite side of the rib of tube.

What is it?
Is it ok to use tube with it?

Can you see the silver getter on the glass or is that is what is let of it - it turns translucent white. I think you have no vacuum.
