Scott 43A - Small Queen -New Perforation..?

Was going through my 3cent Small Queens and decided to take a break. Looking through 6cent I came across this Scott 43a.

Was looking through all my PDF's and Jogil's perforation guide and did not see my stamp's perforation..11.75 x 12 x 12 x 12..Some PDF's state 11.75 x 12 and 12 x 11.75.







Need help just in case this is common and don't realize it...Thanks for any help.

wert: Check the gauge reading of the bottom perforations again.

About 11.95 to 12

Try the Srail Test with the perforations on your stamp. You compare the perforations on the top with those on the bottom and you compare the perforations on the right side with those on the left side. You can use a cut and paste feature program like MS Paint to compare the perforations on opposite sides to see if they match with each other or not. This can be helpful in dealing with perforations that appear to be different from the usual. See

Morning Robert

This is a 'side by side' (or top by bottom...) using GIMP. If I was to see this in real time (not zoomed), it is my opinion that the perfs are very close same top to bottom. Can't say this categorically, as this upsets people ;)

I lined up at perf #10. There is some variance in the teeth spacing across the stamp that could cause different perf measurements?

Be interested in hearing other expert opinions as I am really delving into perfs (and trying to convince myself whether or not I am wasting my time on identifying beyond 1/4 perf ).

Ok...Thanks guys
I will move on to the next stamp investigation.

Again, thanks for your help
Have a good day guys...Be safe.
