I think she was either Nourse Line or Asiatic which were both owned by P and O.
Probably at the time on charter to BISNCo (also owned by P and O!) Nourse Line, Asiatic and Hains later became Hain-Nourse.
I served on this vessel in 1963 as 3rd Mate then for a short time as 2nd Mate.Had been an apprentice with Asiatic and this was my first posting after getting 2nd Mates.She was owned by Asiatic Steam ans was on charter to BI at that time running from Calcutta and east coast indian ports to the far east.These vessels made very infrequent voyages west of suez. I have jopined this community thus it appears I am about 3 years late with this enquiry.Dave
