I believe you can order Duke's gunbelt from El Paso Saddlery.

Typically the Duke carried his belt gun that way in many of his westerns, especially the later ones. His SAA was a 38-40 and the longer rifle cartridge used to tell him when he was running out was indeed, a 45-70.

Here is the Duke's rig from True Grit. I don't know if this is the main rig because it looks a little darker than his usual setup. It does look like his 38-40 Colt though and his iconic big loop 1892 Winchester.
