Collodion Field Camera, c. 1860

Probably French. Walnut, early bellows shape, for plates smaller than 11.4 x 11.4 cm, camera length 57 cm, unmarked brass-bound landscape lens of 24 cm with an insert stop and cap, back and front parts foldable, two of the four bracing struts are missing (can be replaced, camera is still very stable), interesting long back with space for 2 studio cassettes, whereby the focusing screen can be pushed between the two cassettes when transporting the camera to prevent it from breaking, with the two original cassettes A and B (with plenty of decorative collodion traces) and the focusing screen back. – An attractive and well-made camera from the early collodion era.
