06/30/2011. Remarks by Johan Visschedijk: "Derived from the A23 Musketeer, Beech produced 905 'Sport' aircraft in three versions under the c/n MB-1 to MB-905. Introduced in 1966, the first version was the A23-19 Musketeer Sport III. It had an 150 hp Lycoming O-320-E2C engine, two-seat standard interior with optional two rear seats, two windows each side, and 2,200 lb (998 kg) TOGW (take off gross weight). The prototype was registered N2319W (c/n MB-l), and a total of 288 were produced.

In 1968 the 19A Musketeer Sport appeared which differed from the A23-19 only in minor details, and an optional aerobatic version was available. A total of 192 were produced. The last version was the B19 Sport 150 which was introduced in 1972, and 425 were produced till production was ended in 1978. Compared to the 19A it had a new windshield, squared-off side windows, streamlined engine cowling, propeller spinner, and 2,250 lb (1,021 kg) TOGW.

Produced in 1975, N6552R was written off after it crashed on landing in Selkirk, New York, USA on November 1, 1986, due to failed left aileron control rod end bearings. The pilot and sole occupant escaped injuries."
