Pantoscopic camera, made by Johnson and Harrison in England, 1862.

This box-form camera, made by Johnson and Harrison, was one of the first to be designed to take panoramic photographs on glass plates. The images it produced were of a 110º view on 7½" x 12" flat collodion plates. As the clockwork motor rotated the camera, the glass plate was moved past a slot in the camera back, to make the exposure.
