The man bellow with the medals and the beard is my great great grandfather. He was a cossack in the Urals, I have been looking for ages but I can not find what Cossack uniform he is wearing. I really want to know because that could help me find out more about him. I know by looking on his medals that he fought for the Russo-Japanese war, and on the back of the photo it says this photo was taken in 1906, so before the Great War and the Revolution.
I just had the photo colorised so it would help more.
