Yes Brian, I'm back

I was settleted in comfortable for a while, but I was sneeking to the forum checking what's new from time to time (krises, krises, krises

).
Rivkin: you are absolutly right about non-Turkish, it's my error, while I generalised it, meaning the language of Ottoman Empire later Turkey. Mea culpa

.
Well, this sabre is full of questions. The blade seems to be damascene with its grey surface color, but it's mat, and there is no pattern on it.
Different styles of inlay? On the other side of the blade we can see another inscription in Latin speaking about Stanislaw Chomentowski, and it's different in style as well.
"Square-like decoration" visible on the handle is so called meander, popular in Poland and taken from antique Greece. Fittings of this sabre are Polish from about end of the 18th century.
