The Shootist

John Wayne's last movie, in which he plays a gunfighter who is dying of cancer. We can see several handguns in this movie:

Colt Single Action Army

Used by several characters in the film

Great Western

These Single Action Army Replicas, made in the 50's, were the revolvers used by John Wayne in the film. These were a set of 2 engraved revolvers presented to him by the defunct Great Western company.
