Here's a really cool unmarked R. Thomas & Sons made porcelain no-tie insulator found in Spain. This is a super crude piece with the entire surface on this insulator is all bumpy with a snow white glaze not found on other no-ties recovered in Spain.

Measures 4 1/8" tall x 2 1/2 wide. Elton Gish confirms this is an identical match. Unlisted in the books because it was made for export (to Spain) although a few were found in the factory dumpsite. Thomas catalog found in the Smithsonian Museum shows this exact insulator.

Easily VNM+ condition with only a small flake and surface stains (seen in pic) and light use marks. First email gets this very desirable insulator for $850 plus shipping. Price is firm. Don't snooze! Thanks.
