Hi Marius,
1) On the advice and opinions of other members, please see post no 11, and having handled a fair number of blades I am reasonably sure that the blade is a bit older than the rest but by how much I don't know.
2) I don't, I was going to manufacture, as an interesting exercise, the parts myself. As the sword is already an amalgam of 'bits' I see no harm in doing this as any integrity is already lost.
3) Satisfaction, not often I have a blade I can play about with. I would of course inscribe the date e.g. 18th June 2017 into a part of the new fittings e.g. the scabbard locket and somewhere on the guard so that it could never be taken as a period piece, this is of course assuming my manufacturing skills are of a sufficient level to be taken for the real thing.
I hope this has answered your questions satisfactorily but if you have any counter ideas I am open to all suggestions. Many thanks for your interest.
My Regards,
Norman.
