The Norwegian steamship Bjornvik was bombed and sunk by German
aircraft on January 28th, 1942, near the Lizard. Seventeen of her
crew were killed.
Here is a link with full details for you about the ship and the crew. I dont know the state of your research, so I will post it here as additional info:

Position of the ship:
49°57´35N 04°52`02W
About the Luftwaffe units. Its not an easy question to answer but from what I know it had to be a longe range Antiship unit that used
Arado Ar 196A, Dornier Do 24, Blohm und Voss BV 138, Heinkel He 115, Ju 88, four-engined Fw 200 Condors and He 177s and the Do 217s.
These planes were used by anti ship units of KG 30/40/100 between 1942 and 1945.
Other planes wont have the range.
Thats all I can tell you, I hope it helps a bit
Best Regards
