The two insulators shown above are M-3025A made by Lima. The photograph on the left shows the three separate shells. The glaze color is a light tan. The M-3025A pictured on the right was reported by Richard Peterson. Richard's super nice photograph shows the beautiful mottled glaze quite well. Both insulators have the incuse marking "A.C.L.-1" on the top skirt. In August 2000, Mike Spadafora found a damaged unmarked M-3025 and a marked M-3025A on a short connecting line  initials that represent the name of the short connecting line: Angel's Creek Line No. 1. I think Mike has solved the riddle!

M-4604: 16 - 11 - 12 - 6.5 x 13

In June 2000, Paul Greaves and Mike Spadafora found several badly broken specimens of this new style, M-4604, in northern California. It is similar to M-4605. Note lily-shell third skirt and the four long, thin petticoats under the top skirt. The four petticoats are identical to that shown in the 1906 Baum patent drawing (No. 838,163). Lima also made M-4600 which has the concentric rings under the top skirt attributed to the Baum patent. Evidently M-4604 was made before M-4600 with the more sturdy concentric rings replacing the delicate petticoats. Every broken crown they saw was incuse marked: “LIMA, N.Y.” The solid steel pins were cemented in the pinhole. Unfortunately, this unusual insulator was discovered too late to be added to the new book, 2nd edition Multipart Porcelain Insulators. An addendum page for this style is included with each book.
