This is an original USN or USAF Corsair II Attack Fighter Aircraft Carrier Jet EPR or exhaust pressure ratio gauge instrument. The gauge is in good condition with no chips or cracks. It is 2 by 2 1/2 x 4 inches. This gauge measure the performance of the jet engine. The Corsair II was built as a US Navy aircraft and the USAF liked it so much they purchased them also. I don't believe there are any more of these aircraft flying. This would be a great item for someone who collects, A-7E parts, warbirds, and cockpit parts.  Payment must be received within 10 days of auction closing unless prior arrangements have been made.
