Interstingly enough this site from Starpath School in WA state which hosts the Navigator's Newletter archives covered the use of the Brown-Nassau SC in 1998.
Here's a link to the whole Newsletter, and the story on Brown-Nassua is about 10 pages in.

Hope this helps and that I am not repeating information.
