I got this camera Seems to be a collodion one for 15x15cms slides
What is surprising is the markings on front and on top: Maybe a name (the owner?) with Moscow and number 744 engravings, or could it be a Russian made?
On first glance looks like an imported to Russia French camera to me... although I haven't seen a stamped into wood writings like that, usually it's a plaque..
Thank you very much!!! So Adolf Reine is the name on the front plate It's really clear it is probably a French camera imported in Russia before revolution...
