Small no-tie. Not much bigger than a quarter. Inch and a half both ways. Extended inner skirt, threaded pinhole. Likely German. Two markings on top. These old eyes can't make them out. Numbers on one side, circular makers mark on the other. This well experienced insulator looks good, and still has it all. Hairline crack, gray discoloration, wire groove chip, two markings both hard to read, a dirty pin hole and a foreign heritage to boot. Save the postage with free delivery to Mid-Ohio. $25
