William Wynne writes: "N1777W was built at Hickam Air Force Base in Hawaii in the 1960s. It was first completed and flown in 1968 with a Ford Model A engine. After flying only 3 1/2 hours, the engine was removed and replaced with a Corvair engine. The aircraft was shipped to the West Coast, reassembled and flown to the first Oshkosh convention in 1970 where it promptly won best auto engine conversion."

"Between this time and the mid-1990s, the airplane went through three more owners, but was largely unchanged. I acquired the airplane to utilize it as our flying test bed for all my later Corvair engine development work. The airframe logged hundreds of trouble free flight hours with a large variety of pilots. I never kept count, but I'm pretty sure it gave more than 100 people their first flight in a Pietenpol - the youngest being my 7-year-old nephew, and the eldest being Ralph Carlson, the first person to ever purchase my Corvair Conversion Manual."

"N1777W returned to Oshkosh as an honored guest on the 30th anniversary of its last visit. The aircraft was destroyed on July 14, 2001 in a non-fatal accident attributed to pilot mismanagement leading to a stall-spin (see the Carburetor Ice page). The N-number remains registered to me, and it's my intention to re-create the airplane from the remaining parts."
