I'm still digging what it could be, I'v found someone who have 90% same camera as I, and he is also don't know brand name. But he has 8x10" camera, mine is 5x7". It's good. i'm not alone )))) Some people suppose that his camera is japanese clone of "english type". I don't think that I have japanese camera, Japan is to far from Moscow and Petrograd (St. Petersburg) were my great grandfather lived. May be it' a copy, may be russian copy but it's very high quality build.
