Andrey, is it your camera ?
I ask because it really does appear to be in superb condition. These 9x12 cameras seem something of an enigma, common but unusual because so many different manufacturers produced very similar cameras, with what appear to be only minor differences, usually just the shutter & lens. There is quite a difference in quality and sophistication with the shutters & lenses.
However there is one major problem and that's a lack of compatibility between the backs and darkslides, with a number of differing standards for 9x12 plate. holders. So you need the right ones for the camera.
The major common feature is the lens focus bed and the U shape that holds the lens/shutter panel and controls the rise & fall. The panel which holds the lens is either like yours with the quick finder central above the lens or like my Rodenstock where it sits to the right , (looking at the camera from the front).
I've just come across another name making these cameras - ORIONWERK Akt.Ges. HANNOVER, and I'm sure there are more than I listed earlier, this sharing of parts between camera manufacturers is extremely unusual.
Back to your camera, it uses a well proven trackbed for focussing including a rise and fall mechanism, with probably the best shutter then available, and an excellent Zeiss Tessar lens. Why your camera so desirable is the superb wooden body that houses everything, and it's unique.
Oh and Rollex roll film backs are available to fit 9x12 cameras for 6x9 images on 120 film, I just hesitated while writing this to place a bid on ebay and won the ORIONWERK with a Rollex back.
Your camera screams out to be used, I'd love to use it
9x12 (cm) is a great format, the cameras are relatively light & portable, far more so than any 5x4 (inch) camera, I've bought a box of film and have some plate holders, I should add I already have another 9x12 camera and am raring to go . . .
Why am I so optimistic - I already use a 1930's 10x8 (inch) Agfa Ansco with a Dagor lens and its superb, also I use a 1930's Tessar in a Compur shutter on a Crown Graphic again with excellent results, and I have an equally excellent Tessar from about 1913. . . . . . . .
So if it's yours keep it, if not buy it - but be realistic that Ebay sellers $695 staring price is a lot more than the ones I've looked at sold for, I think I've seen 2 Tropica's sold now 2 9x12's and 1 much rarer 5x4.
