Some time ago I bought this 13×18 cm WetPlate camera, I have cleaned up the camera/lens and shot a plate 13×18 cm clear glass.
The lens and camera are marked with H. Malherbe M.Passage Dauphine 24 in Paris. It looks like this camera was owned by the PhotoStudio M. Malherbe in Paris. I managed to find a reference in a journal De La Societe Francaise de Photographie of Januari 1897, the studio is mentioned in here.
If someone has any more information please let me know!
