I'm interested in the four jerrycans. Three are black & clearly for water, but what about the other one is that stone or a light brown? If it was stone or olive drab then it would be for fuel, it seems a bit odd that it is stored mixed in with water jerrycans?
If it was for water then it should not be painted stone as this could have unfortunate consequences for either people or engines as it could be confusing. In the immediate post-war period jerrycans for water were to be painted brown & then later black.
Brown jerrycan denyers will sometimes quote a section of the Materiel Regulations that cover jerrycans suggesting they should be olive drab or stone, but this is in the section on painting POL equipment not water.
The jerrycan of worms is here for those who want apoplexy this early in the morning:

So Lizzie are there any side on views or indeed any photos you have illustrating brown jerrycans for water as this is in the changeover period?
