This picture of a late model MkII shows the cowle over the ventialation grille on the side. The camera is of similar appearance to Mk1 camera but with feet. The top lens was the active taking lens. The viewfinder, a BD625, had a magnifying lens, like the later Mk3, in the hood. There was also a periscope option for the viewfinder hood.
The BICC camera cable connector.
