The prototype Piston Provost first flew on 24-02-1950 with something like just under 400 eventually being built.
40 of these went out to Burma. The Museums aircraft is fuselage number PAC/F/451 and left the factory in late August of 1959 and was flown out to Burma in 46 hours and 10 minutes. It was allocated the Burmese serial of UB-232; later as 2232; and was withdrawn from use sometime around 1981 with a total flying time of 2832 hours.
I believe the Museum will re-apply its Burmese markings.
There is one other P56 Provost known to be in country - ZK-JOT f/n PAC/F/183 of the Subritzky and House Partnership;
And ZK-PPP f/n PAC/F/228 possibly still at Foxpine, although I had heard that it had been shipped to the States, with N397WW being reserved for it.
