Colt New Service

Marvin also carries an early Colt double action revolver. It looks a little small for a Colt 1917. Maybe its a Colt New Service in caliber .38? It's hard to say.

Colt New Service M1917 - .45 ACP.

Colt 1917?

Robert Ryan, in his role of Hans Ehrengard, and Jack Palance, in his role of Jesus Raza, also carry Colt double action revolvers (the gun used by the last one, unlike the one used by Marvin, seems to be built on a large frame. Maybe it is a Colt 1917?
