When Jimmy and Lois are shackled in the cave one of the bad guys puts dynamite in a hole in the wall and lights the fuse which is about 16 inches long. A moment later, the stick of dynamite is laying on the floor and the fuse is now about two feet long.
When Lois and Jimmy fly to Peru the take off in what appears to be a Boeing 377 Stratocruiser. In the next shot the plane appears to be a Douglas DC6.
When Anselmo lights the dynamite in the cave, he shoves it in a hole in the stone wall. However when the dynamite is shown burning in a far shot, it is out in the open, not in the hole in the stone wall.

Anselmo, Jimmy, and Lois drive out to find the treasure in the desert of Peru. The license plate on the car is a dark circa 1952 California plate ( where the show was filmed) with the "California" Blacked out. Not close looking to a 1952 Peru license plate.
