GC10/4B darkening

I have a decatron clock I bought from a member here -- very neat piece that emulates an analog clock on the decatron face. I used a roll-top teak floppy holder for the clock case and it's a thing of beauty.

The clock and the GC10/4B ran for years, no hiccups, but in the last 6 months the tube became almost non-viewable. The face has silvered or darkened.

I can still see the glow from the side of the tube just fine.

I don't imagine there is any correcting the darkening.

Anyone have a nice GC10/4B lurking in their stash for a reasonable price?

Sorry -- the tube is a GS10C/S.

Not sure if the A-101 is a replacement option for you, but I've had one running as a spinner 24/7 for more than 8 years and it's not showing any signs of degradation.

I'm not sure either -- but this clock case is specifically tweaked to the physical height & diameter of the GS10C/S. My particular tube has a flat face which I greatly prefer in this application. Here's a shot of the clock board and mounting.
