CD 121 [070] at least that is as close as I see. It appears that the A & Y are embossed over a W. I do not see this listed and have not been able top locate another one. I will post a few pictures of this insulator, including one looking through the skirt, that picture seems the most definitive to me. Please let me know if you have seen another one embossed like this or if I am just seeing things. Thanks
