Very faint short entry in South point of the North West spandrel; main position of centre dot is clearly South of centre and is very small, party on East.
Kershaw's notes
The oval guide dot is small and merges right with the blue surround. There is a faint flaw in the outer frame line TR above the "8"
Morel's notes
Left oval dot is to the right (4 o'clock) barely inside the white area. There is also a 45 deg. flaw in the top right, just above the "8" forming a sideways V on the top frameline. On off-center copies, the bottom right horizontal guideline extends approx. 5mm right of the main frame.
Stamps from printing orders 1 to 5A were perf. 11.75, stamps from printing orders 5B to 7 were perf. 12 x 11.75 and those from printing orders 8 to 12 were perf. 12.
