I am writing a short piece for my web page www.66squadron.co.uk. G. F. M. Apps was involved with aerial photographic mapping operations, one of the men mentioned in Photographing Canada from Flying Canoes, by Shaw. I am trying to find out the full name of a chap mentioned - "R. Marshall". Can any one help me with this?
Many thanks,
J M Grech
