That's interesting on the L2D Tabby pictures - I've only seen them with the "extra" cockpit windows to the rear. The windows are usually the 1st clue that it's not a DC-3.
Canadian navy capturing a Nazi U Boat off the coast of Nova Scotia during WW2
German submarine U-889 surrendering to the Fairmile motor launch Q117 of the Royal Canadian Navy off Shelburne, Nova Scotia, 13 May 1945. The Royal Canadian Navy removed U-889's crew following the U-Boat's surrender at Shelburne, Nova Scotia. On this, its first war patrol, the submarine had left Germany in March, stopping in Norway before heading into the Atlantic in early April. It surrendered before it could carry out orders to attack shipping off the port of New York.
