Jules,
Before the new REME technology museum was built at Arborfield, all the vehicles were kept at Bordon, which was not freely accessable to visitors. A good few of those vehicles would go out to quite a number of shows around the South, on occasions, I have taken some, Explorer and Austin K6, from memory. The MVT Southsea show usually saw a very large display, from Sherman BARV, Conqueror ARV, Pioneer, Explorer, Leyland Heavy, Ward La France, Antar, AEC Medium, Bedford QL workshop, International halftrack recovery, Austin K6 gantry, etc. The turnout for Beltring used to be large as well. I understand that once the new Museum was opened, some of these vehicles were then displayed so no reason to take them out anymore, as there was now public access. Funding is always a major problem and as with other regimental museums, there is a lot of beg, borrow and favours, I know, having done restoration work while working in the "system", so to speak.
