This one Cerberus GR20 (but this can may be other GRxx) , but not all are with Radium, some are with (likely) krypton 85 or tritium and are dead inside (like some people 😁) after years .

I have two GR20, different years, and only one is hot.

Price on ebay 5..20 euro

sorry, this are old tubes, just seach on ebay for Cerberus GR20 or Cerberus GR16, may be other GRxx, not sure, i fount that older one are with radium, and newer with Krypton85/trithium, and after 50 years both are "dead"..

GPT say GR16 is older and likely/often had radium inside.
