Rifle I.D.

This was brought back from WW II by father in law who served as a Marine . Took the best pictures I could of what markings I could find.
Thanks

Arisaki would be my guess. Unsure of which type.

That was my thinking as well, just don't now how to tell the different types.

Thanks

Type 38. Likely Kokura. Need better pics of the series mark to be certain of age.
