Ed, I've found quite a few so far I can send to you in an email or post them
here if you want. I haven't done much work on connecting the scratches
but that's what should help determine how many times the same subject
was used in a row.
I found three different matty's so far but it's possible some subjects
were used on more than one sheet.

I got this Krause scan from your site. It looks like the scratch might branch
off in a couple of directions from the last L in ball if you can take a closer look.
