Stampcrow, your measurement to the label leads me to believe it is from Plate 11.
My thoughts also.
I had originally just set this stamp aside. Without being able to see the bottom of the frame lines, I thought there was no reason to mark it as a type IV.
I ignored the bit of imprint...
Reading through some USPCS Chronicle articles, I learned about the 2mm spacing. That reminded me of this stamp.
Just not sure if the 2mm space between the frame line and imprint is definitive in identifying this as plate 11.
