Nice little #37, horizontal wove. It seems to have a compound perf. Top=12.25, bottom=12.0, sides are 12.1
Are compound perfs uncommon, or just a result of the quality of production in the early SQ era?
Would you agree this is even compound?
All comments appreciated -
Here is the stamp:
Here is a GIMP image with the top and bottom. P1 and P3 line up, but then the different perfs start to show.
