An elusive style Insulator in a 1915 Catalog?...Look at this style ( No. 41)in the catalog. Second one from the left. I believe no known style of this insulator have been found and this has been posted several years ago, I just found out. This catalog is from the Washington D.C. area, Covers the East Coast. The "41" style was assigned CD 224.5 - but no known examples Thanks Dario..
