Welcome! Glad you found us. We'll get you and Aunt Sue rolling.
The trouble is that you can not picture in your mind what you are trying to assemble. The German Equatorial Mount ("GEM") makes perfect sense when you understand what it is and how it works, but it is an awful mystery to the uninitiated. It is an analog computer, able to find any star in the sky by dialing numbers on those numbered setting circles.
Here, for starters, is a King Size GEM, supporting one of the most famous telescopes on this forum, the Horsetrail Cave. At the far left of the mount (the part holding the telescope to the pier) is a squared box containing a motor (your telescope operates manually; there is no motor). It is attached to the end of a shaft mounted diagonally to the ground. That shaft points at the North Star (if you live in the Northern Hemisphere), and is aligned exactly parallel to the Earth's axis of rotation. When the Earth spins in one direction, that shaft spins in the opposite direction, so that the star stays in view. The other axis twists perpendicularly, allowing the telescope to be pointed anywhere in the sky. Your Aunt Sue did it right! So, you not only get to assemble her telescope; you also get to learn the basics of celestial mechanics, in learning how here mount works. Think of it as an adventure into the workings of her mind, and the minds of all astronomers:
Wait a moment after you click that link, for the page to scroll to the right picture, Then, try searching this Classics Forum for "Jaegers GEM" or "Jaegers German Equatorial Mount," to find pictures of your exact mount.
As an aside, you really should read about the Horsetrail Cave. It is among the best reads on the forum, and it will persuade you that if that telescope can be restored, yours can be, too!
