Yes, this is the Saratov Factory samples.
In 1990, they tried to apply different phosphors. So, at now time
Saratov's Factory are destroyed.
You can look at the different exhaust tube in comparison with the usual green.
P.S.
I also pumped different gases in IN-18 in Russia.
I think so, they must be some experimental lab samples, I have never
seen these in more than ten years. Jens
