Hi Jareth,
The first dirk posted is a Meiji period naval dirk. The fittings are quite different that the WWII naval dirks. It also has a hand forged blade in it. I am the one who sold it to Mike.
The second one posted by M|ke_PL is a WWII era naval dirk. The late war variant can be identified by the lack of a habaki and sometimes plastic fittings.
Funny I picked up another first pattern naval dirk with a forged blade about 2 1/2 weeks ago. I will post some pics in a separate thread shortly
