WT569 did not see squadron service. Was used as a trials a/c at HAL Dunsfold and AAEE Boscombe Down. Full power ailerons and later the first Hunter to be fitted with Bristol phenolic-asbestos 100 gallon drop tanks.
The a/c flew in standard camouflage scheme comprising an upper surface pattern of gloss Dark Green 641 and Dark Sea Grey 638. Underside in gloss Aluminium(silver).
"Archive Hawker Hunter Mk1-5" by Francis K Mason, date unknown features a photograph of WT569 on page 7, with drop tanks at Dunsfold.
Delivered to AAEE on 15th July 1954, tropical trials at Khartoum September 1954 and I think the drop tank trials took place during 1955-56. The a/c became 7491M at No.2 School of Technical Training, RAF Cosford on the 21st November 1957.
Best of luck and do keep us informed of progress.
