Grouping subjects together can become complicating. There is evidence
that the layouts changed on different brands and there is even evidence that they changed within the same series and backs.
There were 107 of the factory 30 "no-prints" that were sold on ebay (that I know of) by the same seller, all of them are in
Ted's group B. Multiple examples of every subject in "group B" were sold with the exception of Lajoie, there were no sales of a lajoie example.
Now if you compare this group of Factory 30 "no prints" to one of the test print scraps
with a similar group there a few of outliers.

Represented on the back of these scraps are:
Conroy (With Bat)
McQuillan (With Bat)
Pelty (Vertical)
Burch (Fielding)
Crawford (With Bat)
Mullin (With Bat)
Lake (St Louis-No Ball)
Willetts
Jordan (Batting)
Wagner (Bat On Right Shoulder)
Willis (Batting)
Bradley (With Bat)
Manning (Pitching)
Steinfeldt (With Bat)
All of these are 350-460 subjects and are in both Ted's group B and the group of Factory 30 "no-prints that were sold on ebay.
But also on the backs of these are:
Marquard (pitching)
Schaefer (Washington
Seymour (Portrait)
These three are 460 only subjects. The Schaefer and Seymour are on the
same card so that could be explained by the possibility of more than one
scrap sheet of these but the Marquard (460 only) is next to a Mcquillan (Bat) a 350-460 subject on the same card together.
