Thanks for letting me know that, Paul - the official documents for war voyages for Norwegian ships often start some time into 1940 (Germans invaded Apr.9), though in this case, for Grey County the document shows her voyages starting early that year. So she had probably arrived New York from Antwerp, loaded then left (for Le Havre) to join convoy in Halifax, as David says. Thanks again.
