I'm trying to either reverse-design or locate a vector source for the design below. I have the full source in a PDF but the person who scanned it wasn't terribly worried about clear details. My main concern is the section just next to the sidewall. It's hard to tell what form that's taking.

Anyone have any suggestions how to clear up the image further... besides stacking them and looking for pixels that don't fit.
