What Goes Here?

This is a demonstration board made by Gracraft Leich that shows what was inside an early wood wall telephone and I assume how it worked. It had all of a phones components on it except maybe the batteries. And the magneto was fastened over on the left side on a shelf kind of left center. But there are 12 holes over there.. 3 each pairs of 4. The bottom 4 are probably the shelf support holes as the are fairly large. The middle set are tiny and the top ones a little bigger. Has anyone seen one of these things and knows how things go together on it?? Would appreciate any help. Its going into a museum and I woould like to have it right.
