This picture features on the back of the AEC Society Gazette, January 2000.
The caption reads:
TGU 205M, a 1973 Mandator new to Amoco UK Ltd. and used
for petroleum product deliveries, was one of a batch sold to Spiers of
Melksham in 1982.
This one was dry-stored instead of entering service, until sold to Society
member Graham Edge for restoration in October 1988. It made its rally debut
in July 1999.
