This month I had the good fortune of getting this 3 skirt Victor Multipart. Since it was not listed in Mutipart Porcelain Insulators (Second Edition), pictures went off to Elton Gish. He has assigned it the number M-3315 (11 - 8 - 6.5 x 6.5). The insulator is similar to a Thomas M-3325, but on the M-3315 the bottom shell has an extended petticoat. For a multi part that is only 6.5" high the crown at 5.5" is very large.
