Pressure Gauge, 2000PSI, PN 12882-A, AN5771-4, similar to use in B-17, B-24

Here is an aircraft Pressure Gauge, 0-2000PSI, made by Electric Auto-Lite.  Measures 2.25in diameter and ~2in deep.  According to the Maintenance Interchangeability gude dated Feb 1945, the AN5771-4 Pressure Gauge was used across many multi-engine aircraft of the US Army Air Forces, including bombers B-17 Flying Fortress, B-24 Liberator, B-29 Superfortress, B-25 Mitchell, B-26 Marauder, and A-20 Havoc.  It closely resembles the model used in these aircraft, but the MIL-G-7734 spec on its data label is evidence that this one was produced after WW2.
