"WB518" was one of the first 10 Mk 6s built, but retained the earlier Mk 5 fuselage. It was originally delivered to the Royal Australian Navy's 817 Squadron and then served in 816 Squadron before being retired and ending up as a memorial on a pole in Griffith, New South Wales, Australia. "WB518" was then purchased by American Eddie Kurdziel, a Northwest Airlines captain and former U.S. Navy pilot. "WD518" was extensively restored and made its first public appearance at Oshkosh in 2002. Restoration of "WD518" used parts salvaged from "WD828" which was written off after a crash into a cabbage field in Camden, New South Wales in 1987.WB518 as of July 2015 was then undergoing extensive rebuilding and is now in flying condition out of Gillespie Field, El Cajon, California.
