Just got this from a smith up in Washington; he picked it up at a gun show a while back for $50. My good camera needs batteries, so I took some photos with my iPad, hope they are of some use to try to ID this blade. 22 inches overall, 18 inch nagasa, shindig slopes dramatically towards the june, which is hiramune. Seems to be o suriage, with the end of the nakago seeming to have been nearly cut through then snapped off, and not filed smooth. Patina on the nakago seems to be oil quench residue as near as I can tell. Someone got happy with the grinder and screwed up the geometry of the kissaki on one side, and the ha. There is an indication of a notare hamon visible to the eye, if not the camera. This doesn't seem like a national treasure blade at this point (pardon the pun), and I plan on trying to salvage it by correcting the obvious flaws and polishing to better see its qualities, unless someone screams "STOP!"
