This is an 1908 Keuffel & Esser Co. Slide Ruler with Leather Case. The Leather Case is about 10 1/2" long & about 2" wide. On the Leather Case it is embossed, K & E Polyphase Duplex Slide Ruler with the # 4088-3S. Some dings & scratches but in good condition. Good quality & workmanship. The Slide Ruler works nicely but on one side has a cracked glass, still works, [see photo] it is Patented june 5, 1900 & dec 22 1908. Nice item and worth adding to a collection. SR#1
