    Help identify Cornell Dublier three dot capacitor

    Hi. Name is Marc from South Florida. I am new here. I test and sell vacuum tubes, but one of boxes of bought tubes had these cornell dublier type1 caps with six colored dots on it. Would like to know if someone can identify it. Will wait until I have privileges to post a pic of it.

            It looks like a molded mica capacitor. My guess using a CDE chart: 91,000pF 100V +/-20%.
            It's a bit odd, mica usually didn't go to such a high capacitance value and low voltage.
            Today, it would be used in electric guitars...
