In this episode, we take a close look at some objects I have been wanting to feature on this channel for a while: a set of engineers' instruments from the First World War, which I received as a gift at the age of 8. Not only are these objects fascinating mechanically, but they also tell the the fascinating stories of the three men who owned and used them during the Great War: Major John Travers Lewis, Major Thomas Sydney Morrisey, and Lieutenant Colonel Herbert Irving Stevenson.
