Hi Tim, not in possession of the sword ...yet. It'll be on its way soon.
I believe the pad is leather....but not certain. I agree the lettering seems suspect...but I have seen, on the net, examples of engraved lettering from around that period (early 18c) and it could be authentic .....but then again a good forger would ensure it was similar....
I also agree about the weight......seems business like, have you any further thoughts on it?
