7304-216 DOWNEY gravity inclinometer. Patented 9/21/91 by Silas Downey and sold by Orr & Locket 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 one is mounted off-center in 36" pine stock with hanghole at end. One screw missing on plate, a few tears in paper face label, mild wear to wood. (GST26)
