Spent a couple of hours at the Museum & filmed the bus in operation. I know nothing about buses but a search tells me it’s a GEA174 Daimler CVG6 with Weymann bodywork. Other vehicles seen were B900TFO, MXX340 and 6342HA – brief details with photos.
The larger photos can be viewed in my photo gallery, watch the YouTube video from the image below or have a quick look through the photos further down the page.
