Good Afternoon,
Hoping I could get someone to verify my findings on this stamp of mine. I have a New Zealand 1d Kiwi with perforation 13.5 all around. There is no perforation 13.5 all around so that's why I'm posting. Also, this particular stamps
design measures 17x21 mm.
I use my own perforation gauge of course, but there is one online you're welcome to try if you'd like to compare.
My measurement: Top:13.66 Right:13.39 Bottom:13.50 Left:13.45

600 dpi.
