I note the perforations along BOTH the right side and the bottom seem to jump slightly. Clearly the perforation "bridge" at the right side shift is longer than normal.

I don't buy into the perf wheel jump theory (or a paper shift theory). What are the odds that it also happened along the bottom edge on the same stamps?

Occam's razor. While not having the stamp in-hand, I would suggest a simpler theory. The stamp was printed normally, then somehow a very small diagonal crease occurred in the sheet during drying/stacking process. The creased sheet was perforated, sold and used. It has since been fully soaked and carefully pressed-out to be unnoticeable today. It would be interesting to see if a crease is visible in fluid.

Consider the following picture with the two diagonal lines representing the double fold of a paper crease. When unfolded, the perf rows jump, but are the same gauge for each half, and depending on the hit/miss pattern, the bridge between holes can be longer or shorter by chance.



That's my take without in-hand study. Thoughts?

I am thinking about that theory...Does make some sense..I looked and looked at the front/back with bare eyes and magnifying glasses...But I can not see any crease or a remnant of an unfolded crease.

Thanks guys for trying to help..On to the next headache..

And perhaps not even a crease, but a small buckle that would not even leave a trace of broken/bent fibers.

Wert: Did you try putting it in watermark fluid as John Becker suggested in order to look for dark lines that may show up in the paper?
