Hi Jim, Jens and CourseEight,
when researching this type of sword I found a reference to several 'unusual' serrated bladed swords being used in battle end of 17c early 18th. The prime function of these 'prototype (?)' swords was to cut armour....however, the soldiers did not like them and they were soon made redundant and discarded.
The reference was via a Google search and I have lost the link
I will try and re-discover it.
However, the hilt does look possible for late 17c/early 18c ....could be one of those 'discarded'.........
Probably wishful thinking on my part
Jens with the long spike pommel this sword may not have been too badly balanced .....if used two handed. It almost seems to be a cross between a sword and a 'hilted' mace.
Regards David
