Bristol 166

A powerful dual control trainer developed from the Bristol Type 163 Buckmaster,
Bristol Type 166 Buckmaster prototype TJ714 TJ714 was the first of two Bristol Type 166 Buckmaster prototypes.
The Buckmaster was a an advanced unarmed twin engine trainer for three crew (instructor, student, wireless operator) to meet Specification T.13/43 developed directly from the Bristol Buckingham. In fact, the Bristol Type 166 Buckmaster made use of components from the Type 163 Buckinghams already built and put into storage.

The Buckmaster prototype (TJ714) was first flown on 27th October 1944. Two prototypes and 110 production aircraft were eventually built, being delivered between March 1945 and April 1946.  Yet again however, most of them went directly to store.
Some aircraft were used however, for the operational conversion of Brigand crews and on communications duties.
One of the two aircraft used for trials at Filton (RP164) was used for Bristol Brabazon de-icing system development trials although it was eventually scrapped at Halton in 1958.
