I still have the radio, so I think I may have the manual too.

When the radio was found to be working, you'd remove the parts and assemble them to the circuit board and complete the radio in its case. They were needed to attach them on the breadboard assembly. The little squares of circuit board sticking out of the board to go into the radio were to be used for the IF's. In the ebay photo, the schematic in the box was to be glued over either balsa wood, or craft foam and the included spikes in the bag to the left were inserted in key locations to do a sort of bread board assembly of each subsystem until the radio was complete and working. The manual was full of theory of AM radio, conversion, amplification, oscillators, etc. I may still have a copy of the manual, I need to check at my partent's house ( built one in the early 80's when I took electronics in high school).
