hope someone out there can help. What is this and how was it used. Found here in western Kentucky. Thanks in advance for any assistance. Thanks to Stan and Ann, James and Raine, and Dustin for following info: Item appears to be a fuse cut-out assembly probably for a transformer on a pole. Large white porcelain piece in front is a fuse holder. Also serves as a switch simply by pulling the fuse. Smaller porcelain piece in background is a lightning arrestor.
