Hello Detlef and my congratulations to you on winning this most wonderful piece. If I had placed my bid like I thought I had it might have been the other way around.
Imagine My surprise when the auction ended and I saw the price that this went for and found I had forgotten to place my bid like I thought I had.
Well at least I know that it has gone to good home.
I agree with Lew on this except I think it could date from 1890 to about 1910. Look in the grooves for small holes where wire might have been fixed to the hilt right next to the collars. On almost all of the ones I have the wire decoration seems to have been added after the knives/swords were finished. Again my congratulations on your win and remember if you ever get tired of looking at this I will be more than happy to give it a new home with lots of new friends.
Robert
