We have a drawer full of these here, mostly glass enclosed types. They are made by Victoreen, Keithly Instruments, and Welwyn. There are various values from 1 megohm to 1 megamegohm (1,000,000,000,000 ohms) at various tolerances. What values were you looking for? ---------------------- Doug Tymofichuk dougt at cancerboard.ab.ca
