Ken, I think it's the camera angle that makes the sets of holes on the back wall appear to be out of alignment with those on both sides. If you look at picture #3, you can see one bottom rear hole exposed below the existing shelf, which is mounted in the topmost position.
What about the post(s) in the freezer section on the right above the basket seen in picture #5? Is the basket supposed to slide out, maybe?
My guess on the copper rectangle is that it's a trim piece around a thumb wheel to adjust air flow control from the freezer's evaporator below. I've seen different iterations of this system on later Coldspots with separate "master" cold control and air flow control. The air flow control is used as a temperature control for the freezer section. Ideally, settings on each control would be about mid range for a fridge temp of around 37 and a freezer temp around 0.
I can see how this would be a tempting fridge, but finding the parts to make it fully functional would probably more difficult than resolving the defrost issue. If you can work around the shelving problems (you could perhaps remove the crispers entirely and store them, or use them in the freezer section if they'll fit), it would certainly be a conversation piece as a drinks/overflow fridge.
