Someone gave me a bunch of stuff from the shop of a dead tech a few years back and I remember a whole pile of strange, small, crts with similar markings on them. I have often wondered what they were and if they had any value. I left them there because I could see no practical use for them in the TV and radio hobby plus the space around here is limited. If anyone needs one I think they are still there. I would be most interested just to know what they were used for
