This offer is for a pair of 1940-50's vintage dual engine Oil Pressure Gages, type B-9C (formerly AN5772-2) and made by US Gauge., labeled for engines #1 & #2 and 3 and #4.  Likely used in late WW2 or post WW2 4 engine aircraft such as B-29, B-50, C-54 etc.  Do your own research to confirm.

The instruments are in very nice condition for their age.  The dial markings are clear and the glass and cases are intact. Both have been painted on the outside glass with the operating limits of the aircraft in which they were installed, see photos.  The #4 pointer appears to be loose but might be able to be re-inserted firmly.  The glass for #1-2 needs cleaning from the inside, which is usually simple to do, but I'm leaving that to the buyer. Would be a great addition to your collection.

Please note that seller does not represent that this specific instrument was actually removed from any aircraft cited in the description, but that any documentation referenced here is evidence that it is the same type number and/or manufacturer's part number, used in these aircraft, or if such numbers are not available, the item closely resembles photos of the aircraft's instrument panel.  We do our best to link instruments to specific aircraft, but Buyer accepts responsibility to perform the research to verify the item's use in specific aircraft.
