Here's a scarce French made Radio Strain insulator embossed: Modele Depose (front) Pyrex (reverse). Rarely see this marking on this uncommon style of radio strain. Early Registered Design insulator. Approx 7 inches long. 6 small bb pings and about dozen and a half tiny tic marks scattered around. Small rub mark with match head flake beside it. Factory ground pontil on one end.

First email gets this scarce antenna radio strain for only $70 plus shipping. Thanks!
