A 2¼ square roll film negative. A deck view of the Type 12 frigate Yarmouth (1959) alongside the south-east corner of the fitting out basin in John Brown & Co Ltd's shipyard at Clydebank. The photographer is looking forward and to port from the rear of the Gunnery Direction Officer's platform above the bridge, showing various communications equipment on the forward and port bulkheads with their canvas covers rolled back. A voice pipe is in the port forward corner and the azimuth repeater next to it has a canvas cover. The Gunnery Direction officer's sight on the extreme right is covered in canvas.
