Well here are the clues ! It has the larger rear windows and upper window so its a Messenger 4A. Its fitted with a wooden prop -short exhaust stacks -has no wheel covers and what appears to be a registration on the fin can be seen in a blaze of red .

Therefore on the basis of this – the aircraft which fits this description bearing in mind probably less than twenty were civilianised from RAF service is G-AKZX.

What clinches it in my estimation is that it was registered to Neville Browning until it was written off at Rochester 1965,
