Just an update. I searched the BT387 series with no result. I have emailed the Norwegian Archives to see if they have copies of the original Crew Agreement.
I am given to understand that the Norwegians published in two volumes of Sjøforklaringer fra 2. Verdenskrig Vol. I & II. This listed full crew names and casualties taken from what I believe were copies of original Crew Agreements. So there may be transcription errors. Just hoping they still have the originals.
Also discovered that there was a British vessel with the name GYDA O/N 167564. Ex Danish, registered in London in June 1940. She was deleted from the British register in 1945, no doubt returned to her Danish owners. Need to check her Crew Agreements to see if there is any mention of Edward or Archibald Ramsay.
Thanks to Merchant Navy Association Archivist, Billy McGee for his help and advice on this one.
Will keep you up to speed on any further developments.
