Picture # 2 from previous.......I would appreciate help in identifying this insulator. I think it is a jade blue milk (really jade aqua milk seems more accurate but I don't see this reference anywhere so jade blue milk is the closest) with F skirt: H G CO (note no periods) and the R skirt is PETTICOAT/B. You might think like me that it is a [045] however there is no jade blue milk listed. Index number [070] does list a jade blue milk but the F skirt embossing has peroids, i.e., H. G. CO. Your thougths would be appreciated.
