Mk 2 Carrier water can

[Tony Smith]

How late were the 2 Gal cans manufactured for the military?

I have a few W^D 20lt jerry cans from the early 50's, and had thought that these superseded the 2 Gal types.

But on Ebay UK at the moment is a 1955 dated 2 Gal can (https://www.ebay.com.au/itm/VINTAGE-...YAAOSw8b1gSKcV)

Were they made much later than the mid-50's?

Meanwhile, yet another listing on Ebay shows and ad for an Australian Oil Company from 1949 promoting surplus British 20lt cans filled with engine oil.

So by 1949, the British Army was already disposing of surplus 20lt Jerries, but was still making 2 Gal cans in 1955.
