That said, these things are going just a little bit too far for me!
I recall many years ago getting an issue of "compo" (Composite) rations in the Army, and imagine - a couple of the tins were marked "WWII stock"!
I understand that some of the tins issued in WWI are still perfectly edible. Imagine corned beef from a cow that died almost a century ago....puts another meaning to "best by" dates!
Here are some more "wonders"......By the way, if you look at the prices - well, you won't be in a hurry to order....!
