 I might try sending it to a US polisher and pay for him to polish a "window", a small section of the blade to see if there is any grain and thus if it is worth a true polish, older or WWII machine made blade.
 
 Another possiblility is to try the nihonto guys over at the Swordforum.com under the Nihon-to section with your pictures.

I have no experience sending sword overseas, do you have any suggestion which polisher I should send my sword to?
