Here are some pictures of the blade. Not the best pictures, but i will take some scans later.
If the signature is fake, when is this likely to have been added? Is the blade still 17th century and the fake signature added when it was made? Or is the blade more likely modern, and the signature added say in the 1900s?
What sort of value you would put on the blade, with real signature and with fake signature?
Thanks,
Lewis
