Not sure if a question like this even belongs here but while dreaming of well polished swords I saw this absolute rust bucket somewhere. I've got no experience whatsoever with neglected nihonto, so hopefully someone with more experience can help me out here.
The shirasaya (is it??) looks very iffy, I've never seen it done like this. What is this? A 'fake' or something very unusual? The blade itself I also have no idea about. It might be genuine but it is in absolutely pitiful state. So even if this one were the real deal, would it even be possible to bring this back to a state where people would want to look at it?
These pictures are unfortunately all I have.
