Here's a rare wax resist porcelain insulator that was found in Colombia. Says "MUESTRA" (front) "Ref. #321" (reverse). Muestra is the Spanish word for Sample. This style insulator is not found in the Electroporcelana GAMMA porcelain insulators catalog and the dark chocolate glaze is darker than all examples of Gamma insulators found in the country. I believe this is an American made insulator that was sent to Colombia as a sample for electrical contractors or to the power company in the country. I assume #321 is the catalog number for this example.

Measures 3 1/2" wide x 3 1/2" tall. Looks to be mint condition! Never seen another! MINT condition.

First email gets this unusual porcelain insulator for only $185 shipped. Thanks!
