Here's one of the sheets I'm working on. The back plate was used on two
different fronts on this sheet so there are two subjects for each scratch
one is a SC 150 Fact 649 and the other isn't for each scratch so I think
it's possibly the layout for one of two sheets used for the 649 printing.

There are three different scratches or partial scratches on this sheet that
I randomly marked on the template I made. So far there is no way to tell
what vertical row each scratch was in or how many vertical rows there were.

The scratches in the bottom row are bolder than the other two and
easier to find but the two upper scratches are faint and hard to spot
so I'm still looking to confirm a large number of subjects in the two upper
scratches.

The X's on the template indicate if one or both subjects have been confirmed for that particular scratch.

This is just a work in progress so I'm sure there are mistakes but there is also good evidence for most of this sheet layout. There are a few examples where
more than one pair or group are in the same order on two different scratches on this sheet.

If anyone would like to check there PD 150's for the unconfirmed scratches
the template would give you an idea where to look for them for each subject.
