A lot of research has been done on Plates 12 through 45.  This group, which follows directly after the Black Plates falls within the period that the Maltese Cross and Numeral Maltese Cross were in use.   Another feature of this group of plates is that Roller Flaws occur throughout.  Plates 12
thourgh 16 show a progress break at the top of the north-east star square.  Plates 21 and 22 have a small gap in the north-east star square.  Plates
22 through 27 also have a progress break in the top of the north-east corner which on 23 through 26 forms the so called "north-east triple break."
The 1842-43 10 and 1 O'clock Ray Flaw occurs on more than half of the plates from 26 through 45.  This first section illustrates the different Roller
Flaws and the effected plates. These Roller Flaws are prominant throughout this stage of the Penny Red production and serve as a "blue print"
to the plater.
