Grumman G-23 preserved wearing the fake markings of a US Navy FF-1. It is in fact ex Nicaragua Air Force GN-3, delivered in the late 1930s. It was withdrawn from service in 1942 and ended up in a scrap yard. Rescued from there in 1962 by J.R. Sirmons and flown to the USA in 1966 as N2803J. Acquired by Grumman who restored it as seen here and donated it to the then US Naval Aviation Museum at Pensacola.
