B64-567. GRAVITY INCLINOMETER. The Downey Level. Patented 9/21/91 by Silas Downey and sold exclusively by Orr & Lockett Hardware of Chicago; examples we've seen have a range of different stocks and it may have been marketed as a separate level attachment. This is in a 28" x 3-3/4" red-stained softwood stock and the vial is off center. Some small stains on the paper dial and nickel mostly worn off the vial surround, but works smoothly. A couple of paint splotches on the reverse side of the stock. Condition: Good+, Estimate: 120-240
