Hi again,
I'm afraid it's a fake. See here:

I'm not sure I'm skilled enough to give an advise, but I'll try anyhow:
1) buy as many good books about a sword as you can before making a sword purchase
2) search the Internet and especially all the forums, then search again, then search again, then ask and only then make a purchase
3) always try to handle the sword by hand before making a purchase
4) only buy from guys who have a return policy
