No doubt about it. You have perfed it correctly.
Scott lists a 12 x 11. In your image, the perfs are aligned a bit to the left of the 11.5 perforation lines. Try it at 12 and see.
If you look at the last 3 perfs on right of horizontal perforations, they are drifting off center so this is a clue to go to something more towards 12,
Did you look at a perf 12 alignment? I would start there to prove it is wrong. I do not know anything about this issue, but perfs in catalogs are usually rounded at least to 1/4 perf so a perf 12 on US could be 11.75 to 12.25.
If that is a Stanley Gibbons Instanta perf gauge, use the numbers on the right to be exact about the perf. The gauge measures to 1/10th of a perf
Redid perf match. Definitely not 12.
I still get 11 1/2 by 11.
I always use the edge dots around the gauge in the holes of the perfs, I find it easier and more reliable than trying to match a line to a perf tip that no longer exists. With the back of the stamp facing towards me.
I think I've correctly got this stamp as 11 1/2 x 11. But I see no such variety in Stanley Gibbons. My eyes can't take too much more of this. Arghh!
