Why were iron rations, from WWI, called ‘iron‘?
First option is find somebody who is good at soldering. Second option is for you to replace the pipe.
despite a lot of research I cannot come up with a published reason - just descriptions of which one is Iron Ration (1907-1922) The first attempt to make an individual ration for issue to soldiers in the field was the iron ration, first introduced in 1907. It consisted of three 3-ounce cakes (made from a concoction of beef boullion powder and parched and cooked wheat), three 1-ounce bars of sweetened chocolate, and packets of salt and pepper that was issued in a sealed tin packet that weighed one pound. It was designed for emergency use when the troops were unable to be supplied with food. It was later discontinued by the adoption of the Reserve Ration but its findings went into the development of the emergency D-ration. I can make suggestions - they came in an iron tin the rations looked like pieces of iron they tasted like iron they were called that to make the soldiers think they contained a lot of iron and would build up their strength
First two guys said it. My other suggestion is that you look for more ruptures. It is unlikely that the pipe only broke in one spot.
