ORIGINAL, PERFECT CONDITION WWII German Luftwaffe Luftschraubenstellungsanzeiger (Prop Pitch Indicator) Fl.18505-1 (9-9500.60). This electrical instrument was used to indicate the angle of the air screw in the form a clock dial, with the Me109 E engine prop beginning at the 12:00 position. This was used in all early Me109's, although the Fl. 18503-2, 9-9500.31, and 9-9548 B were used in later versions. Apart from changing from electrical to mechanical, the difference was marginal. Mounted on the main instrument panel.
