This was picked up by my Grandfather somewhere in his many travels. He was a British Military Officer during World War II and later a Diplomat. This piece has been displayed in my fishing cottage for many years. Always a conversation piece. It’s specifically designed for military naval operations during World War II. This depthometer comes with its original wooden case, adding to its historical authenticity and charm. Perfect for collectors interested in aviation and military history, this unique piece serves as a tangible reminder of the significance of naval technology during wartime. From my personal collection. New items listed every week. Many loyal repeat customers. You never know what will be for sale.
