Bill:
I, too, once read some kind of reference to Raynor and Maple Bluff, but I can find nothing that indicates he ever worked on the course. An aerial of the course today shows nothing that could be considered similar to Raynor's highly stylized, almost geometric work (squared-off fairways, sharp lines, classic template holes, bunkering). In fact, Maple Bluff from the air looks similar to Midlothian.
The brief course history on the MB website credits Tweedie with the original nine.
