US Plan of minelayer Olaf Tryggvason
This plan from a US Recognition magazine of 1944 shows the Norwegian minelayer Olav Tryggvason, which served in the Norwegian Navy from 1934 until 1940 when she was captured by the Germans. The Germans named her Albatros II for a few days in 1940, but she spent most of her time in German service as the Brummer. Clearly this name change didn't reach US Naval Intelligence, as she retained the earlier name in this 1944 plan.
