Hi Iain,
Age, I do not know exactly as I am no longer in touch with my learned Hungarian friend, but I will endeavour to touch base with him again.
The blades vary in age but the sword as a sword appears to my eye to be circa 1800-1860...others may suggest they know the people still making them today
I've had several and lofty provides another but they all follow a chosen form, be it because of a required regulation pattern or a guild or workshops choice I am unaware.
