For Soviet tubes, we see lots of nixies with 1992 date codes, so dekatrons with like date codes are no surprise. As mentioned, if it was used in their defense industry, then they probably would keep making the parts, until that equipment was no longer in service. In any bureaucracy, that could be a while. The Soviet Union collapsed ~August of 1991. Probably took a few months to close down the factories.
In "the West", most tube production, other than CRTs and microwave magnatrons, ended ~1975.
