Here we have three different porcelain pieces. On the left is a porcelain tree insulator measuring 4"x3"x2". The embossing reads SCOTT C CUTTER/OSWEGO ILL on one side and JULY 23-29/PATENT NO. 1721657 on the other side. The metal bracket is rusty but could be cleaned up if you want to remove it. It has one small chip on the end of the curved ridge visible in the photo. In the middle is a dry-spot insulator from Australia. It has a deeply incuse marking on top in the shape of the Australian continent with E.C.C.A./PAT. No. 7926. The underside of the top piece which detaches is marked 5020 A. The bottom is marked U-8 (the 8 may be a B) 77/1 and 2731. When you take it apart, the inside is marked 30 AMPS/REG NO 759645/MADE IN ENGLAND/500 VOLTS. All of the copper components to attach the wires inside are present and no damage except for a very small chip on the top piece On the right is a fire plug insulator marked UNIVERSAL/NO 1003 on one side and PATENTED/APR.13.1910. on the other. It is in good condition except for some bottom edge chipping measuring about 1" wide associated with an open bubble. Take all three for $60 and that includes Priority Mail shipping.
