The second bottom left chart is incomplete. Approximately 5 columns are cut off - the bottom left side has 8 columns in the 10x10 block, the bottom right chart starts with 4 columns in the 10x10 box, there's the previous 3 columns from the left side (those are not present in the image 9- Bottom Left b), that leaves 5 columns completely missing (2 from the bottom left b 10x10 block that's visible, 3 from the 10x10 block continuing on the bottom right chart). Also, the pattern is not a scan but photos, meaning parts are hard to read. Cleaner photos or actual scans would much appreciated - this pattern would need a good archived version!
