This insulator is just plain AWESOME! A very unusual colour of lemon yellow with just a tinge of lime green mixed in to give it a very odd colour. Insulator is very crude with 2 huge lightly blackened carbon bubbles chasing each other around the skirt nose to tail. Up into the dome there are a lot more smaller bubbles, some nice steam and gunk swirling the pinhole plus a very nicely swirl start to the threads and glass surface rippling. There is 1 small no feel um annealing crack at the base which is 1/2" tall and stable. Insulator is beautiful underlighted or backlighted.
