Kindjal with Gurian-Adjarian type blade

[Gustav]

For viewing pleasure a Kindjal with Gurian-Adjarian type blade, with twisted damascene rods in the grooves. Likely somebody was keen to collect the bit of gold from the maker's stamps on the blade. No stamps on the silver parts of the sheath, but this kind of niello work, as was pointed out to me, is characteristic for silversmiths coming from Van.

I guess the whole would be around 1840-50.

Remarks, details, opinions?
