David,
Are you wondering if the original design on your course was a Maiden or a Double Plateau or whether if it was restored as original what it was?
I take it there are no drawings or construction instructions that exist. As an aside, I don't know how much Raynor relied on drawings for his designs. If he did, how much of his portfolio drawings exist today?
Have you searched for aerial and ground photographs that might help you? I think I saw you are in the Baltimore region. Perhaps the Hagley collection, local historical societies, museums, libraries and the like might have a collection of photographs, newspaper articles, and other archival material that could help you. Craig Disher is one fellow you should contact if you feel the search to date has not been exhaustive. He also has a software program that, with the right sources, can bring out tremendous detail about vertical features and quantify heights down to a foot or so.
