It looks like an early Type 30 bayonet with a Kokura arsenal stamp.
JEDEM DAS SEINE
but dont you think the marking looks kinda shoddy?
seen as there are large gaps in it and the fact that its off center and slightly rotated, it just doesnt look as much attention to detail was given to it, all the other i have seen looked like this,
looks like a repro from China
Thanks Bob !
