WTK: Info on WWII Bayonet

I have a WWII Jap Bayonet that I cannot ID the Arsenal Markings. I has the 4 balls with 3 on the outside of the center ball but it has some markings next to the 4 balls that I cannot match up to any Arsenal Markings on the net. It has the Hooked Crossguard, contoured grip, Screw fasteners and birds head contoured pommel.

I am posting pictures and I can email pictures to anyone who wants them. Just send me your email.

I would also like to know the value. This is a Marine bring back.

Thank You!

The three circles stamping is Kokura Arsenal. Which was the contracting and supervisory arsenal. The other stamping is the sub contractor mark. Sorry that I cannot identify the subcontractor stamping. There were more than five sub contractors. These sub contractors were not weapon manufacturers in peace time. They made looms and electrical goods. You will need to comment on the quality of this bayonet. As the war went on quality became poorer as less experienced sub contractors were used.
There is a note in my book that the Type 30 bayonet was used by a number of nations occupied by the Japanese after WW2. It MAY be a local stamping. The subcontractor stampings in my book are next to the Kokura stamp and NOT underneath it. Korean ????? Value in UK trade sell £30+ but Jap stuff is not popular in the UK. Hope this is of help.

These seem to sell on e-bay for $35 to $95 depending on condition. Sharpened ,rust, pitting etc.. reduces the value. If you have some proveance to substantiate the war trophy status that could boost the value substantially.

I posted this in another thread and I got a response telling me it is from the Koshikowa/Nagoya Arsenal. When I Google Koshikowa/Nagoya Arsenal I do not come up with any info.

Thank You.

Nagoya has two smaller cicles inside it. This aint it. Koshikowa used it until 1935 and this is produced after that. Thus, Kokura.

Finding out about unusual stampings is all part of the hobby. Enjoy your bayonet!

Koishikawa, Tokyo was the location of the Tokyo Artillery Arsenal, then Army Weapons Arsenal, and after a huge earthquake around 1933, it was moved to the location of the Kokura Arsenal. The four circles are suppose to represent a stack of cannonballs, from the old Tokyo Artillery Arsenal.
