Allan Barns-Graham, Aldershot oven, hot water cylinder at mess bure, No date

The Aldershot Oven does not actually appear anywhere in this picture. I have constructed a number of improvised field kitchens in the ' 80s for civil defence work in the UK of GB. The oven cooking stove shown is a drum oven. From my personal knowledge of Army Catering Corps training of young chefs, recruits where NEVER allowed to start on these improvised methods until they have completed a first year of basic catering training. The exception is always wartime. The 3 half barrels in a row, are the catering dish washing facilities & they are fed with a Lazyman boiler drum system, it was usually an oil barrel with a long tube on the end of the funnel, the tube delivers cold water to the bottom of the barrel, displacing the already boiled water upwards toward the pouring spout on the side. This meant that cold water did not remain cold for long (as the fire was immediately below where it was directed to). Such water was usually left about 20 mins to get it hot enough to be used. The dish washing barrel basins operated with the furtherest from the Lazyman Boiler, being the washing basin, then the next closer one, was rinsing and the closest was always sterlising as it always had the freshest hot water first.
That all said, it does make for an interesting picture.
