Old Schwinn Traveler: I don't know how to attach the derailleur hanger

So I'm very new to bike mechanics (and cycling in general). I wanted to clean this old Schwinn Traveler (~25 years old?) up to use it for commuting. I used a great book and some help from my LBS and it looks pretty good. However, I have one problem. I have no idea how to get the rear derailleur hanger back on. Every picture or diagram I've seen looks nothing like this and I have no recollection of how it was attached in the first place. Pictures are here.
- There is a hole in the hanger where there was a small bolt and a D-shaped nut. I can't seem to find them. Even when I did have them I couldn't determine how the nut would hold this thing on. And there is no corresponding hole in the dropout
- There is a bump on the inside of the hanger that prevents it from lying flush against the dropout. So if I tighten the nut the bump causes the axle to be pushed out, misaligning the wheel.
Has anyone worked with this design before? I'm sure it's really obvious and I'm just missing it but I have no idea. Thanks for helping out.

That small bolt and D-shaped nut are to space the axle into the correct place and help align the derailleur. The axle should sit at the very end of the dropout will full engagement of the axle bolt. The derailleur hanger bolt consists of a bolt and a d-shaped fastener that is threaded. The bolt goes through the hole in the derailleur, screws into the d-shaped fastener and the lip on the d-shaped fastener holds it in place.

Thanks for the link. I'll definitely buy a new one. But I don't really understand how the lip holds it in place. Is the lip supposed to be on the inside or the outside of the dropout? Is it supposed to space the derailleur out so that the bump on the inside doesn't prevent the axle from staying all the way inside the dropout?

The screw holds the D-shaped nut on the back side of the claw hanger:


Then with the nut loose enough, slide D-shaped nut down the slot in the dropout (rounded end first). The D-nut then rests at the very end of the dropout slot. Then tighten the screw to clamp the claw hanger in place. The bump on the back of the claw sits in the dropout slot and prevents the claw from rotating around the screw & D-nut.



There is also another D-nut that goes on the other dropout so that the axle will be located evenly when pulled all the way back. Although I typically lightly tighten the right side first, then slide the left side so that the wheel is centered between the seatstays and chainstay.
