WE MFG.CO. / PATENT / DEC. 19 1871 (back) W.U. /A This amazing crude insulator has a base shaped like a roller coaster track. There is some nice milk and nice bubbles in the insulator. There is an inside surface annealing crack in the inner skirt just to the right of the milk patch. I might have over looked a flea bite or two.
