Hello,
I also got this beautiful Bichaq. Because of the fuller work I think it was made around 1900 in the region of Trabzon, maybe in Surmene.
The handle is made of black horn with mother-of-pearl inlays. The metal mountings are of nickel silver and the scabbard is covered with goat leather.
There is an inscription on the back of the hilt, it would be great if someone can translate it
Total length: 31.5cm
Without scabbard: 31.4cm (really

)
Blade: 20.5cm
Best
Robin
