I guess that there isn't a lot of variation among these CD 106 Birminghams. This one is embossed: BIRMINGHAM // 1 / NO. 10 with SDP. This is EIN [030]. The PG calls for 'straw' colored pieces. Mine seems more pale peach. I see no yellow in this insulator, so to me it's not straw colored. This one was in service, as it has a clear wire groove rub. Neat piece, not rare, but still a different embossing for my shelves.
