Frequent GCA poster Dan Moore may be your best bet for any information re. Westmoreland. A fairly extensive timeline put together a year or so ago by Dan for a GCA Langford outing doesn't mention Westmoreland. But the timeframe of 1921 was when Langford was doing some really interesting courses -- Culver Academy (1920), Bryn Mawr (1921), Ozaukee and Wakonda (1922), the original nine at Harrison Hills (1923), and the sadly NLE Acacia (1924).
