It is likely that when you apply voltage to the filiments, they will either light dimly and/or burn out.

There is always an outside chance that I am mis-reading what I see in the photos, but I would not be optimistic. I have seen bad tubes with getters that look far better than the ones pictured in these photos. Still, you will need to test it anyhow to tell for sure.

Believe me that I am not an expert. But looking at the getter flashing inside of the neck of the tube kinda looks as though it has leaked. I don't see the bright silver and charcoal gray. But that being said, I am NOT trying to rain on the parade. I sincerely hope that this tube tests NOS.

Best of luck, and I look forward to more on this thread.
