In the group picture this is the insulator 3rd from the left. Stamp embossed on front skirt HEMINGRAY / No 9. On rear skirt PATENT / MAY 2 1893. Has sharp drip points. This one has a huge double bubble in the back skirt above the PATENT. Condition is pretty good. One chipped off drip and on other side a row of three with the inside halves chipped. Good thing is there is no bruising above the chipped drips. Also on the very top of the dome is what looks to be an embossed circle or zero, it could just be a mold line, but it sure looks embossed?? You will not be disappointed! $30 plus S&H and insurance.
