Grumman G-111 Albatross (N10GN)

Somebody screwed up some paperwork along the way, because it's not a G-111 and it's also not an HU-16B. The serial number proves it (and BTW that's not really its 'correct' serial number either.) It was built originally as a model UF-2 (a long-wing variant) for a US Navy contract for Germany. Post-1962, the UF-2 became an HU-16D. The HU-16B was the long-wing conversion of aircraft built originally with short wings (80 ft. span) for the US Air Force. 146427 is its assigned USN Bu. Aer. serial (aka "Bu.) number, but it's proper "builder's" serial aka construction no. (per 14 CFR 45.13a) is G-445 (out of 464 production aircraft.)
