I personally think it is an odd ??? color ... But I'm not an expert on some real or altered stuff. You be the judge. Dwayne Anthony? Did any one else handle this piece at the national. I immediately questioned it, but it isn't the normal radiated colors that one might expect. Maybe a low dose of some form of radiation? Or an odd batch of glass at the time? Glass was poured in huge vats so there had to be more than one of something in another item or insulator....... It has been offically determined to be an altered color by RADIATION! The original owner verified the radiating of the insulator per icon chats.
