Simple modifications of the classic field camera led to the development of detective or magazine cameras. Here are some easy-to-understand "missing links": 1) M'Ghie & Co. (also spelled McGhie), Glasgow. Detective Camera, a 4 x 5 in. field camera from 1885 in the form of a small carrying case, with a near-mint brass-bound lens, Wray London 5.6/5 x 4 No. 4130, a discreet focusing lever on the side for the rear standard, and an opening on the back of the case with a view of the focusing screen back.
