i thinkthe sword is genuine. It looks like an older blade, probably cut down. It is hand made and probably 250+ years old. The parts are genuine and antique but nothing special. It is hard to say value from a few pictures. Can't say is retempered, or if it has hagire etc. If it were offered for sale "as is" from the pictures shown i would think it would bring $4-800, but it could be a very old naginata-naoshi and worth a lot more, or it could be a retempered blade with an hagire and worth the value of the parts (couple of hundred). Where are you located? maybe you could atttend a club meeting or bring it to a future show
