This one has the diamond embossed on the top of the dome and the Pennycuick dimple on the inside, top of dome. There are signs of wear along the edges of the wire groove along with a very small wire groove chip. There are just a few scattered pings, a combo open bubble with a bit of flaking at the base of the skirt. There is also a chip right at the beginning of the threads. Still a nice looking insulator and only $10 plus shipping.
