Two websites of note for you -
http://www.coltautos.com/
Is Sam Lisker's excellent Colt Autos site, complete with takedown instructions, history, serial number ranges, etc.
http://www.wwa.com/~dvelleux/19031908.html
Is a more general site, but still fun to read.
Remember, Bogart used a Colt Hammerless to shoot Maj Strosser in "Casablanca".
