Modified Admiralty Pattern 301. An intriguing knife, which I think started out in life differently to the way it has ended up.. Stag Scales. 3 ½ inches Sheep's foot blade. Overall length 8 inches. The marlin spike has been removed. The (original) blade position now has a saw blade. The saw blade although a reasonable fit, when closed extends slightly further than scales. Hopefully this expanation works, please email for any more details. I cannot find any marks. Flook pages 130. 131, 132 refers. So the knife could be from 1915, it is an interesting knife and a must for the serious collector.
