Nice job Marc.
I have plenty of info on Colt's philisophy and vintage pics, so it wouldn't be hard to be accurate.
As for the architect? I'm sure that some of the architects that frequent this site could do the job well enough. In the UK, the bunker work I've seen by Steel, on Colt's courses, is poor. Hawtree did a nice job at Whittington Heath but the bunkers are simpler there.
