Never seen anybody mention that stain before. How can you tell it's water and not some other kind of liquid?
There is a huge water stain on 116v, spanning the whole page from top to bottom. It is visible (only?) in the 365 nm UV images of the multispectral scan set, like MB365UV_007_F:
The (A) lines are the stain boundary. Near thet top of the page the boundary is confusing but the stain may span most of the page's width.
There seems to be another boundary (B) in that area. Could it be that someone rubbed chemicals over the "michiton" text too?
All the best, --jorge
