The Buccaneer fuel system was developed prior to the introduction of Fuel Flow Indicators which incorporated the Amplifier circuits for the signal from the Fuel Flow Transmitter. This Buccaneer Fuel Flow Indicator and Amplifier Test Set therefore has two functions in one set; Fuel Flow Amplifier and Fuel Flow Indicator testing. The Test Set will test the Fuel Flow Amplifier Part No. 7807-04000 (perhaps similar to C0874) and a range of Indicators, Part Nos. 3D659, 3D593, 3D307, 3D703.
The Buccaneer Fuel Flow Indicator as seen on an actual cockpit is Type 3D444, (Cat. No C0222) a circular instrument calibrated from 2-14 LB/HRx100 and strangely, the Test Set does not state that this is a type it can test. The Test Set has a different Indicator Part No.3D307, installed on its front panel as a Master reference. When acquired, this test set was fitted with two 4.5V zinc-carbon batteries (as pictured) but have been removed because of they were leaking.
The Test Set was produced by Service and Repair Division before it was called Aviation Service and Repair. Elements of the Buccaneer Fuel system were made by Dowty and they had a Test facility at Staverton for the Spey engine. It would seem that Elliotts were involved in the measurement and Indicator equipment.
