There were in fact four different marks of this aircraft. The Mark I (illustrated), was superseded by the Mark II which featured a longer fuselage, and in turn the Mark III which featured floats with encased wheels. The final version was the Mark IV, three of which were exported to the Imperial Japanese Navy which featured a raised upper wing. The R.A.F. did not accept the Pintail into service possibly because whilst the upper view for the crew was first rate the downward view was somewhat lacking.
