Would anyone know anything about this sword or the signature on it? Or if it's an authentic sword?

Is there a way to tell if it's an authentic sword or a fake one? From what I've figured out I think it's supposed to be a Ww2 officers katana.

I don't think Trystan or Kyle would have even translated the writing if it were faked.  The fakers rarely get the mei correct.

 

The rest looks like a legit civil sword, re-fitted for the war.  If you want an evaluation of the age of the sword, I'd post it, with pics of full-length, naked blade on the Nihonto Forum.  They'll want a measurement of the straight-line cutting section from tip to notch on the back edge.  Like this:

It has a rather worryingly deep chip in the blade edge. I wonder if its fatal?

[kyushukairu]

As Bruce has correctly stated, it’s an authentic sword, and in military mounts, though the blade itself is a lot older, and quite likely from the Edo era.
However, whether the signature is genuine is another question… I have attached some shoshin (genuine) examples of Masanori’s signature for you to compare yours with.
