Q353DAJ Bedford TK/HCBA military domestic tender HCB Angus fitted the first of these for the RAF in the early seventies, this has a higher roof line which looks fibreglass. The MOD always went for a budget machine and they suffered for it, as opposed to many civilian brigades speed didn't matter as most sites were fairly small. Must have been preserved hence Q plate. Finished service life 1986. This photo at Duxford rally I think.
