Hi,
I think it's not because nobody wants to scan the boxes you're asking, but it's more that nobody have theses boxes indeed. At least members of this awesone site.
This project is, and will be in progress without time limit.
All the scans provided here are free, and each member upload what he wants to, without any obligation.
So you'll have to be patient and use all RSS feeds provided in each section to keep track on the updates.
What I suggest is asking directly ebay sellers to kindly send you scans you're looking for, then upload them here

It's also a good way to contribute to the project, and sometimes it works.
By the way, it's my last warning, NO MORE ANNOYING LINKS TO EBAY, thx.
