German Submarine, UB-110. Photo of Control room looking aft, starboard side (by Tyne & Wear Archives & Museums) This image shows manhole to periscope wall, valve wheels for flooding and blowing. Hanwheels for periscope gear, air pressure gauges. The UB-110 sunk after attacking a merchant shipping convoy near Hartlepool in July 1918. It was then salvaged and transferred to Swan Hunter Wigham Richardson Ltd. Dry Docks (Wallsend), with an order to restore her to fighting state. The order cancelled following Armistice and she was scrapped thereafter [via].
