This unique item is an Antique Cast Iron Gear-Driven Apple Peeler.  It was made by the Reading Hardware Company and is likely from the late 19th Century. It features a large geared wheel for hand-cranking and a table-mount clamp to secure it. Crank and Gears work and it all appears to work fine. Great conversation piece and interesting to look at and work it.  Good luck on the bidding!
