One of the things I especially like about paper modelling (and Google!) is that a new model will often inspire an internet search - which then makes the model in question even more interesting.
A few days ago I came across

They offer a model of a German WWII rescue buoy, developed after an idea of Luftwaffe General Udet. During the Blitzkrieg large numbers of German planes were forced down over the English Channel. The idea was that survivors might be able to swim to one of these buoys, inside which they would find food, water and dry clothes. They would raise a flag, so that either a Dornier seaplane or a small 'Schnellboot' (fast boat) would be able to spot them and pick them up. Although nearly 100 were built and anchored in the Channel between the English and French coasts, no one was ever rescued this way. Quite a few lost their anchors and ended up on various beaches. The one in the picture finished on the Dutch beach near Castricum (north of Amsterdam). Another one ended up on the island of Terschelling where it gradually disappeared into the sand. In March 2016 the remains became visible again.
