Here's a desirable two-piece Light Yellow Straw CD 402 glass dryspot insulator from Italy. The cap unscrews to allow a wire to be inserted through a separate hole to prevent leakage. Embossed: CAP 1219 . FLAMREX 1960 (front) TS (rev). This is an unlisted embossing.

These are rarely offered and this one easily grades VNM++ condition! Only 1 match head flake otherwise MINT!

First email gets this hard to find insulator for only $135 plus $10 shipping. U.S. $160 Canada (This cd books for $300-350!) No need to pay auction prices or premiums! Thanks!
