First world war 98 bayonet numbered 1

First world war 98 bayonet numbered 1. The bayonet is marked Waffenfabrik Mauser-A.G. Oberndorf a.n. and dated 1916. The bayonet is a low numbered example with the serial batch number 1. This is the lowest I have ever seen! The bayonet retains a large portion of the factory blueing and would be hard to upgrade.
