Motorists driving across Norfolk and Suffolk this summer may come across an unusual vehicle in their path.

The Sentinel Steam Bus, from Bressingham Steam Museum, will be travelling to various local rallies - as well as participating in a wide-ranging national tour - starting this weekend, when the 82-year-old bus appears at the Strumpshaw Rally.

Built in 1932 and registered for the road as KG 1123, this was originally a flat bed lorry made by the once famous Sentinel company of Shrewsbury.

As a long-lived heritage vehicle, it has had many lives and, after 10 years in preservation, it entered its perhaps most intriguing phase as a passenger-carrying steam bus.

Using surviving documents as a guide, it was fitted with a 32-seat replica wooden bus body of Sentinel's steam bus design.

As well as the Strumpshaw rally, the bus will also be appearing at Palgrave, Weeting and Henham Park.
