The war-winning Wehrmacht-Einheitskanister

[old man emu]

Forget the V1, V2 and Me262, the Wehrmacht-Einheitskanister was Hitler's real war-winning secret weapon. Without it, WWII in Europe would have been a rehash of the trenched stalemate of the of western Europe in WWI.

The original design is still the best.

Except when they rust.

I have one with a pinhole vent !.

I've found the black poly jerrycans are superior to the steel ones. The steel ones are prone to internal corrosion and pinholes due to vibration. However, the originals certainly were the dux nutz in the era before advanced plastics.

I just found a jerry can that was made in 1952. It is still in good condition. Those original ones were properly made. Some time later, the design was copied, but the ones made then did not follow the design to keep the welded seam below the outer surfaces of the can. Obviously plastics are now the cheapest way to make containers, and result in a more durable object.
