These tiny insulators are a really cool conversation insulator just because of their very weird style. The colour of this one is a yellow green, but you be the final judge in the colour. Colour is accurate in the pic but I have a daylight photo available of this too on request. Condition is VVNM, just a few tiny pin pricks and a bird peck to the top side of this piece. There is a little bit of small annealing fractures and nibbling inside the pinhole from the threads and that's it. Displays great. Book on yellow green is $125 range. $80 delivered for this great insulator.
