Packard did it between 1948 and 1950. They were really nifty when new but a drawback was the relatively short half-life of the isotope, as they aged they were more and more difficult to see at night. IIRC a regular correspondent on this site repainted some for a friend of his with radium paint he got somewhere. Probably need an NRC permit for that now. Perhaps some of the intrument repair services still do it.
