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. 1914 Abney Level Manual: https://upload.wikimedia.org/wikipedia/commons/8/83/The_Abney_level_handbook_%28IA_abneylevelhandbo1935calk%29.pdf SOURCES: https://jasonclarkeantiques.co.uk/products/mark-i-bell-pattern-sextant-with-full-accessories-by-heath-co-of-london https://sextantbook.com/2010/01/07/a-box-sextant/ https://rochesteravionicarchives.co.uk/collection/historic/verners-pattern-prismatic-compass http://www.mhs.mb.ca/docs/people/stevenson_hi.shtml
