b61-266 INCLINOMETER. Short Version of Melick Patent. Rarest of the Melick inclinometers, 3-1/2" square, originally thought to have been cut down until one was found with its original box. Much rarer than the cast iron mantleclock version if not as pretty, with only a handful known. This one has some moderate nickel loss, but complete and works smoothly. From the collection of Don Rosebrook. Good+ 300-600
