Here is one i know you don't have. 250 embossing. only the 'hem' and 'ray' show. and the 'm' and 'r' are 1/2 missing. then the 'N' is the only part that shows from the "no 9". it looks like the top of of another insulator touched against it when it was hot.

chip damage affecting 10 drips or so. no damage upstairs.

unique. $20 plus shipping. find another like it.
