Got another one, it looks like Randall #Gambler and at the same time San Francisco bowies (Will & Finck, etc.), wood handle has a couple of cracks, leather sheath. It is well polished, the blade is oxidized, there is a feeling that it is Damascus, some reflections show it. It is rather difficult to capture the surface, as it is polished and black, so I took a few photos. For size comparison shown next to #10-5. The balance is good - on the front cut of the bolster.
