First off, never heard of it.
I looked at what I assume is the
primary source for you. I can find Curtis Pond on an
old topo. I assume Curtis Hill is on the pond's SE side. The photo of the course from the article looks like it is facing SSE over the course. The photo later in the article looks like it is taken just a little bit right of south, with Mt. Pomeroy in the distance (has the right profile). It also says the the clubhouse remains would be visible from the shore down by the intake, and that would fit.
What I'd suggest is contacting John R Greene (mentioned in the article). Lives in Athol (Bearsden Drive, I think), has written a number of books about Quabbin, still gives talks. Can't imagine he wouldn't be happy to talk.
Interesting stuff in
here. But I'm sure you've already looked around a bunch.
