Today we found what we presume was my grandfather's Dietzgen Navigator's Case U.S. Navy. I found a web page, and lost it, where it describes that while Dietzgen was a German founded Company, this particular kit was made between 1936 and 1942 in Chicago. My grandfather in 1936 was serving as a lieutenant on the U.S.S. Cuttlefish (submarine) and then for several years of shore duty he was doing Navel inspections at various production plants, such as Fairbanks Morris production of deisel engines for Submarines.  He was on the U..S. Lexington in 1940. In 1941 he was prompted to Lt. Commander to take command of the U.S.S. Shark which was sunk in early 1942 in the pacific. I guess he didn't take this item on the shark with him. I suppose he left it ashore with his wife. Otherwise it would be on the bottom of the ocean.
