Cord exporting from the factory

Does anyone know which port Cord used to ship cars to England and Europe.
Also did they use the same shipping agents and shipping lines every time.
I am trying to find out the number of right hand drive cars exported to England,which I assume came in via the Port of London.
From details I have, and registration details known, I have arrived at a figure of 30+,and allowing for cars that went back to the U.S. and other places after WW2, and cars that were scrapped,I think the final total must be in the region of 50.
Any members who have RHD cars,and bearing the dealers plate RSM(Automobiles)Ltd of London, could they please let me have the details from the Cord plate with serial,body and engine numbers,and English registration (tag) numbers if known.

Thanks.
