Section removed - I should've said duck egg blue for the small cab panels, not sherwood green. Oops!
D8243 probably had full yellow ends when in service, as this photo shows it wore the original two-tone green livery as a carriage heater in 1978.
Edit:
Just found this website which states:
D8243 new 02/61, w/n 02/69 - FYE, small arrow logo, original numbers with 'D' 01/67. (Into departmental stock as ADB968000). No data panel when withdrawn. After use as pre-heating unit, loco cut up by V Berry, Leicester 02/91
