Claim: The Bay Super V had 17 different versions but only 15 of them ever flew.
Evidence: Beginning in the late 1950s the United States aircraft company Bay Aviation (formerly Oakland Airmotive) produced nine twin-engine conversions of the Beechcraft Bonanza called the Super "V" Bonanza. After production was shifted to Canada in 1962, five more aircraft were built for a total production run of fourteen. Serial numbers as high as SV117 are known to exist; SV101 was later rebuilt into SV116, and SV110 and SV111 were skipped, hence known production is fourteen aircraft.
