Around the time of the LFB F12 acquisitions in the very early 1950s the brigade was transitioning to diesels, and bought large numbers of diesel Merryweather dual purpose appliances. Do we know if these were bought after the petrol engine Dennises, afterwards, or whether there were mixed batches of both which had overlapping delivery dates?
We do know Dennis did not take long to get into the diesel engined business in London, with the F101 appliances, which had the monster 12 liter Rolls Royce marine diesel engine, and these were seemingly enough to unseat Merryweather, although London still bought their turntable ladders on AEC chassis.
This is ex Fire Service College, Moreton-in-Marsh, which I expect accounts for the London registration. It is reportedly a 1951 example and remains in preservation. Previously part of the FSNMT collection at Weedon.

I have since learned that for a few years London bought both F12 and Merryweather diesel dual purpose appliances, but ceased buying petrol powered units after the first F101s were delivered in 1955. There was a small batch of AEC dual purpose appliances later, but almost all new acquisitions were F106, F109 and later series Dennis units.
