I'm trying to repair the damaged latch and shade curtains on this 4x5 RB-D (photo attached since there seem to be many variations on these things). There seems to be a missing metal hook of some sort on the door. And, there's a pin in the bottom of the front standard. Is the only thing missing the hook on top or is something missing from the pin? Can someone show me what it looks like?

I was going to make new curtains out of some black cloth and just glue them to the door and standard. Anyone have a better way to do this or will it work okay?

Thanks,
Dan
