Nice line up, showing the transition in the late 60s and early 70s from petrol engine Bedfords to Perkins V8 dIesel engine ERFs - something that was happening in quite a lot of British fire brigades during those years when loads of brigades switched to diesels.
Some went for Dennis appliances with first the AEC AV 470 (F106) and then the Perkins V8 (F108), while several bought the relatively new Ford D series with either the Ford turbo six cylinder 300 or the Perkins as well. Dodge also joined in with the Perkins, and supplied several units to Bristol, as a less expensive alternative to ERF.
