Just ended on e-bay. If anyone can install the pics permanently on this site, I'll be grateful.

Why?
Well, look at this one, from Artzi Yarom's personal collection:
http://www.oriental-arms.com/item.php?id=1501
They are identical, down to the soldered-on signature on the back of the scabbard ( with the exception of the broken-off finial on the e-bay's one).
Moreover, there is a third identical one, currently actively auctioned. I cannot ID it for now, but will do it as soon as the auction ends.
We are talking about an incredible coincidence of having 3 identical high-class items from the same 19th century workshop. It tells us something about the power of serendipity and the alleged impossibility of the lightning striking twice.
This pattern must have been in high demand and rightfully so: what a beauty! Hope it was bought by one of the Forumites!
