[QUOTE=Pat R;1601932]I'm really happy with the progression of this sheet the last two days.
The most recent discovery is a little involved and I'm terrible at trying
to explain these things via a computer but I'll give it a try.
I was pretty sure before but now I'm positive this sheet mirrors a SC150/649
sheet and I think this is one of two 649 sheets that were printed.
The recent Sheckard discovery left only two spots on this sheet that remained
with an unconfirmed 649 subject.
The names and empty slots (?) in red are the 649's.

While working on the 649 same sheet position matching pairs combo I
came up with these two.
Attachment 251102
Neither Bransfield or Ewing were on this sheet so if this PD150 sheet
mirrored a 649 sheet and there were only two sheets which I believe
is the case, Branfield or Ewing would have to match one of the two
unfilled spots.
I haven't found a Bransfield that matches what I consider the main (lower)
scratch subject. But I do have a Bransfield that has a vertical scratch.
Attachment 251104
I thought this Branfield could be a continuation of these two Conroy vertical scratches.
Attachment 251105Attachment 251106
While looking through Branfield scans I found this one that matches one of
the vertical Conroys.
Attachment 251107
I also found this Bransfield that I'm confident is a lighter version of a Conroy
secondary horizontal scratch.

Attachment 251113
I found a Bransfield that matches the Conroy from the main scratch on this sheet.
