Hi looking at purchasing a NZ marked 1907 bayonet dated 9/18, but it is missing the locking mecanism. I recently purchased a bunch of 303 parts and with it came what I think is the complete locking mecanism for a 1888 bayonet. I can purchase a 1907 stud and spring online but am in need of the locking nut (sorry don't know the correct term). Is the locking nut of a 1888 bayonet compatable with a 1907 bayonet locking stud?
