The New Dennis No2 Trailer pump

We have just acquired a new pump. New to us, and new (1944) relative to the old (1938) one. Although the old one has run well, and has had quite a lot of money spent on it, it still boils in service, and is getting tricky to start. It also needs a repaint, and the cylinder block flushing out.

The new pump has the hose locker, as opposed to the earlier pattern hose trough. This means that hoses are kept dry in the rain. The new pump has a number of other advantages: it has built-in tail and indicator lights (not original, but certainly an early pattern, and they don’t look out of place), it has a fuel gauge (but it may not work), it has a silencer and air filter, a complete magneto (although it apparently needs a new condenser fitting), but most importantly, it has an anti-freeze-filled cooling system, that is in turn cooled by a secondary water tube inside the header tank fed from the pump and discharged to the floor. By contrast, the old pump takes pump water through the engine and straight onto the floor. This means that the engine can freeze up if not adequately drained for winter, but also all the crud and scale from the water gets deposited in the engine. The new pump had drain valves almost everywhere. It also has brand new tyres.

The bad bits: the correct towing eye had been removed and replaced by a larger eye. This would not be so bad if the chassis had not had an inch cut off the end! So rather than a bolt-on swap, there will be some work to do. The front leg had been removed but that is almost back on now. And the locker lid is corroded, but an almost perfect lid came in the spares and that is almost fitted. Most of the drain valves are seized, but being bronze, should free up easily. And the three radiator-hoses are perished.

And sadly, the paint is the wrong colour, being a darker shade of greenish-grey, so it will need repainting anyway. But the original bill of sale from Dennis Bros to the Ministry of Supply for £236-10, dated 28th July 1944 is included. The pump was delivered to Lancashire, and given that the Blitz was over (and the V1 and V2 bombs never reached Lancashire), the pump probably saw little active service.

I am a director of a small (and very technical) business, a committed Christian, a Reader (and preacher) in my local village church, husband to my dear Frances, am interested in heritage railways, and heritage fire engines. I currently run a group that displays wartime and early post-war fire engines at 1940s re-enacting events and steam engine rallies. O yes, and vintage cars and motorbikes, and we live in a Victorian railway station.
