FRU 305 was a 1945 Bristol K6A with Strachan L55R bodywork, originally numbered TD 774.
In 1952 it was taken into Southampton Works where it was rebodied with the FPO59R body shown.
There were bits of the original body, bits of Brush bodies from 1938 K5Gs - and bits found by H&D.
It ran in this form until 1968 when it was withdrawn and sold, ending up in Dublin, where it was last seen in 1972.
