This is a horizontal format tailboard camera. The lens is too short to cover the whole format and would have been used with the quarter-plate reducing frames. The lens is marked Rouch but the initials are not W.W (either H or JJ), the serial number is also much too high for the period if it is in the same sequence as other Rouch lenses. No other Rouch is known, possibly the lens was made for them and badly engraved. The lens appears to be of the same period as the camera.
