Description
You are bidding on a NICE used example of an WW2 German Luftwaffe 0-3 kg/cm2 Druckmesser (Pressure Gauge) Fl. 20504-3 as used in the late-war Me109 and Fw190 fighter aircraft!
The 0-3 kg/cm2 Pressure Gauge and measured the pressure of the MW50 or GM-1 system which sent Methanol into the engine. This added an extra boost (similar to today’s Nitrous Boost in cars) that lasted usually 10-30 seconds. It was located on the side console or main instrument panel of the Me-109 and Fw190.
