When Dingo's effects are presented to the Marshall in his office the holster rig and pistol are completely different from the rig shown in the closeup at the beginning of the film as Dingo rides into town.
At the theater the band plays an introduction with the conductor playing a violin while alternately using the bow as a baton. Near the end of the number he plays the violin for three notes with no sound; then, he holds the bow as a baton and the three notes are played.
(at around 18 mins) Dingo's widow and Dooley are in front of the marshal's office and Marshal Ware hands Dooley Dingo's gun and personal effects. Dooley throws the gun and belt onto the ground and later he throws the five Double Eagles on the ground at the same spot. After they leave, Marshal Ware picks up the five coins, but the gun and belt are not on the ground and were never picked up.
