It looks like you have a 'Thai Police carbine', the bent bolt and cutout wood beneath the handle, and the M1 carbine type sling cutout in the butt are correct for this carbine.
It should still be in 6.5x50mm Japanese, and was made from a normal T38 rifle, not a T35.
They are neat little carbines and should make a fine hunting rifle as is.
They are valuable as a collector item too; so don't modify it; maybe $300+/-.
