Hey, count me in on the OCD thing. Had it all my life but only diagnosed at 40. I'll bet you dollars to donuts I'm in good company on this forum, though! Anyone? Anyone?
Looks like its solid from one end all through but not including the other ender. I remember getting a 19 x 40% cwr one time a few years ago myself. And I've only ever found one 20 x 40% (all '68D with the date written on the wrapper) solid roll myself also. I think I found both rolls right around the same time from two different banks just over 2 1/2 years ago. Since its been so long ago now it makes me appreciate just how difficult either one are to find.
