Does anyone recognize this Donald Duck story?

I remember a Donald Duck story that I belive was from the 70s.
Donald Duck was visiting a junkyard and he found something made of gold inside a large stove, and then the Beagle Boys stole it and escaped from a building at the end of the first part.
The first part ended with Donald and Scrooge fighting, and then someone walks in and yells at them to stop.

The problem is that I never found part 2, and so I have always wondered - who was screaming in the end?
The person was not actually seen.
