You may want to click on the original size to get a better look at the arrowhead with the tip broken off in the dome of the far left insulator. The previous pic showed the front of the same insulator. It's not really an arrowhead. Not sure exactly what it is but it is over an inch in lenght. I saw the amber in the front at first and was then marvaled when I looked at the back side. How you like this one Mr. Watkins?
