Here''s a picture of a Knox RT insulator I got for christmas. I know that KnoX was purchased by Porcelain Products and some insulators have both marks (Knox and PP), but does anybody have one marked with a W like this one. Anybody have and idea as to what the W stands for ? .Second picture will be a close up of the W marking. Any help will be greatly appreciated. Billy
