Sorry BSD this one is not the cockpit of the Enforcer or the Cavaliar.
I know the aircraft you are referring too. Cavaliar Aircraft Corp acquired the design rights in the original P-51 from North American in the 1960s. In 1968 Cavaliar flight tested a modified P-51 as the Turbo-Mustang III powered by a Rolls Royce Dart engine. They then set about a more ambitious turbo-prop conversion using a 2,455 s.h.p. Lycoming T55-L-9. Two airframes were put in hand. First flown on April 19 1971, this conversion was named Enforcer and that same year Piper Aircraft acquired full rights from Cavalier.
In Sept 1981 a contract was placed with Piper for the construction of two new prototypes which became the PA-48 Enforcer. These were also powered by the Lycoming T55-L-9. and flew April 9 and July 8 1983.
The challenge aircraft was not a turbo-prop and this paricular aircraft type first flew later part of 1950s.
