All i remember about those kits is that there not named after the actors or films, so it might be a job to find them, the names are loosly based on the films (i think its something to do with copyrights)
good luck in finding them
EDIT
Andreas minitures make alot of Cowboy kits, a great stagecoach and front of a bar
they also do John wayne, The Magnificent, Butch Cassidy and The Sundance Kid
they might be woth a look at for the figues your after
