Photoshere 6×9 cm with magazine back.
The Photosphere 6x9 was patented by Napoleon Conti in 1888. The model with "Hanau" plate-changing back was offered for sale by la Compagnie Française de Photographie around 1895.
This silvered version has its viewfinder, ground-glass screen and 2 wooden plates in addition to the magazine back. Very hard to find in this format.
