Another lucky find was yet another Pinco porcelain spacer insulator. This time it was the plus shaped one I had been searching for a long time. It is marked PINCO L-3235 PAT. 2,291,212 Lima N.Y. That makes 5 different styles I have now. Numbers 3181, 3190, 3234, 3236 and this one. Makes me wonder how many there are. You can see pictures of my other ones on previous posts. Just type in my name to see my posts or PINCO. Very neat and heavy piece.
