The Bristol Type 73 Taxi Plane was a three seater with passengers carried in side by side seating behind the pilot. That was the idea, but with two passengers it could not get off the ground. It was developed into the Type 83 Primary Trainer featuring tandem seating for pilot and pupil. The first six entered service with the Reserve Flying School at Filton in 1923 until being replaced in 1931 by the D.H. Moth. Bulgaria received one, Chile took 12 and Hungary received five. There was a one off Type 83E which featured the 250 h.p. Bristol Titan. Total production of all types 28.
