Aye Ess, a couple of very nice paintings showing how the RFDS has moved backwards from a nice reliable and safe multi engine aircraft to one of those single engine widdowmakers.
The Drover is illustrated in its Mk3 guise, post '61 lycoming upgrade, but before the Mk3a mod to the tailplane. this aircraft was a Mk 1, 1f, 2, 3 and 3a progressively I think. Did it ever make Mk3b? (increased MTOW)
