I have. I've spoken to the polishers we all know here in the US and other than the pitting it is in good shape. The sword cost me nothing but the price of a polish for an early Shinto or late koto blade. One polisher said "That looks like a nice older blade in reasonably good condition. It should be completely restorable. That might even be a koto (old sword) period blade. Should be interesting."
It has plenty of steel left for a polish, a beautiful hamon and no openings at all.
