Happy Harold is an 80-year-old Hastings trolleybus, converted to diesel in the 1950s to become a tourist attraction.
The vehicle fell into disrepair but has been put back into pristine condition in a project by the Hastings Trolleybus Restoration Group.
To get Harold back on the road it needed a class 5 MOT and Rossetts of Eastbourne was the nearest testing station to Hastings able to do that class of test.
Problems arose, however, when it was discovered that at 15ft 6ins the bus was too tall to enter the testing station. Phone calls to the next nearest testing station at Ringmer revealed that the entrance to their testing bay was only 14 feet high so that was out of the question.
Group chairman Ion Castro said, "It was a bit disconcerting really, the next nearest testing stations were at Lancing or Canterbury and at 22mph it would take all day to get there, so we decided to take the poles off the top of the former trolleybus and it drove in with only inches to spare.
"I've got nothing but praise for the assistance and patience for the staff at Rossetts — they certainly went the extra mile to help us."
