Schematics for a .22 pancake magazine

A colorful document showing how to reload the somewhat complicated pancake mag.
It tells you how to make a hand-loaded .22 pancake magazine with the following components:
 5 - loose rounds 
 5 - empty clips 
 2 - chrome hubcaps 
Making this would take good familiarity with craft and decent familiarity with rifles.
In the upper right corner is a note: 'First discovered by Dr. Rade.'
