Tom, the TSUBA is a genuine one. The whole looks a bit assembled, as the mounts are from different times and sources. The brass HABAKI is probably a later addition, the TSUKA looks like military, as does the SAYA. It is difficult to state something substantial on the blade. I have the impression that the blade is sharpened down to the HABAKI, so there is a slim chance that it might be a pre-war one, but the condition of the blade will make any judgement difficult, even with better photos. If possible, show the blade to an expert or a NIHONTO club near you.
