The Spitfire throttle quadrants varies depending on the Spitfire Marks. In the Merlin powered Spitfires the quadrant body was basicly the same. From Griffon powered Spitfre Mk XIV onwards the quadrant was new design. Handles and details also varied depending on whether they were equipped with a bomb release button or Gyro Gunsight handle (GGS). We can offer all quadrants with required equipments.
Spitfire Mk II – V Throttle Quadrant
The first marks were equipped with mixture lever and booster cut out lever.
Here we have a Mk V with only throttle lever section. The quadrant plate is made according original Spitfire part. The booster cut out lever will be added.
Spitfire Mk IX and XVI Throttle Quadrant
With the Merlin 66 engine the quadrant was equipped with idle cut lever and hasn’t the mixture lever. The earlier version with Merlin 63 engine was without the idle cut-off lever in quadrant (the cut-off valve was fitted below the instrument panel). The quadrant plate also differs from the early ones. This quadrant is detailed as the original ones: There is a gate when pulling the throttle lever to the combat power with the sign and a back limiter for the airscrew control lever.
Mk IX GGS Throttle Quadrant
Here we have a repro construction quadrant for late Mk IX and XVI Spitfires equipped with Gyro Gunsight. The lever was cut and the large GGS handle was added. This handle is original and needs some restoration. Also the connection to the lever is not correct in all detail but shows how it was fitted to the quadrant. The handle was connected to the gyrosight with bowden cables and when pilot twisted the handle he adjusted Span & Range Graticule in the sight. The electric wire comes from the handle button and goes to two terminal block: one for bomb and the other for camera.
We are going to develope the quadrant and make a set where it is connected to the Gyro Gunsight. Though it may take some time as it needs a cockpit section also.
