I'm not sure that this is a WWII blade. An oil tempered blade would look frosty at the temper and the pattern is consitent. Oil tempered blades were usually machine made blades and did not even have a hada (grain).

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.
