Thanks for the quick replies and links.
Unusual story on how Dad paid for his passage. He was a model engineer, and, built, model steam locomotives. Somehow, he knew, or, somebody that Dad knew, knew the ship owner. Anyway, however it happened, Dad traded a partially built model steam locomotive for his passage.
Myself, my mother, and, my two sisters came across later (October 1954) on the Empress of Scotland. North Atlantic in winter time. Pretty exciting passage.......
