I have an 8x10 Korona that sounds like the same version that you have, so if you need any detailed pictures let me know. I did a fairly extensive refurb on my 4x5 as well, and I can say that unless you have some extensive damage, all you should need to do the frame repairs is some sandpaper, a thin metal file, a few clamps, and some quality wood glue. My rear rail was in pieces when it arrived, and the front standard was a mess as well. I was able to fix the whole thing up in a weekend and it's now my favorite camera. The 8x10 is wonderful too, but I don't have a pack for it yet, so it doesn't get used as much. They are really fun cameras - congratulations on your find.
