Liquidometer
Oil Quantity Indicator, 4 Tank Selector, Liquidometer, EA-48-16 B-29
$39.50
This is an authentic vintage quad-tank Oil Quantity Indicator made by Liquidometer, PN EA-48-16, as used in the US Army Air Force's Boeing B-29 Superfortress (see photo of B-29 Flight Engineer's instrument panel with a red dot showing instrument location).
The knob situated below the display rotates to oil reservoir 1 thru 4 (see photo of display partially rotated), indicating the quantity of oil in each from 0 to 85 gallons.
The instrument is experienced, showing evidence of its use, but is in exceptional condition for its age. The dial markings are clear and the glass and case are intact.
