Thank you. I am tempted by 'Peterel' as she was evidently spelled, which fits better than most things I have tried. I see she was sunk off Shanghai with loss of life and some crew captured.
I am awaiting better information on a civilian of the right name and age whose death in 1942 in Malaya is recorded by the War Graves Commission, but without any other details. This might be a forlorn hope but I have not found another proof of death so far...
