B66-270 MANTLE CLOCK INCLINOMETER. L.L. Davis No. 1. Second version of the classic inclinometer as manufactured by Davis prior to the formation of Davis Level & Tool, with detent screws at 2 and 10 o'clock and locking screw on top. The signature gold highlighting is absolutely perfect as a result of it having been kept in a custom made mahogany box. Brass dial oxidized but undamaged, needle and vial perfect. From the collection of Steve Dice. Fine 400-800
