I was looking through my SLs when I noticed my Miller (Piedmont 350) had multiple crop marks. I've seen plenty that have the small marks on the center side/top/bottom and one or two with a horizontal line at the top. I haven't seen one that had a 'T' mark at the top like this one. It also has a right side crop mark, a center bottom crop mark and two small blue marks in the bottom right side border. Any others like this out there?
