Japanese Diamond 60 makers mark?

[Guamsst]

I have a Korean refurb Japanese type 30 bayonet with a makers mark of a diamond with the number 60 in it.....could be 09 I guess.

Anyone know what the makers mark is? I am guessing it is a restamp but there are no signs of an original Japanese mark.

Solved, I have been informed it is Chinese post war, more info in the Jap rifle forum.
