Mike "Rain" Spadafora- Olympia, WA. These Victor M-2435 and M-2430 multiparts were rescued from an old power line in Montana by Rain, insulator hunter extraordinaire. ;-) The M-2430 in the center is a seldom seen version with a factory 1 inch pin hole . The two M-2435's each have installed reducers to 1 inch from the standard 1 3/8 inch size. Therefore, they fit our 1 inch tilt pins on this sharp curve.
