That aligns with my original assessment, admittedly based upon subpar seller images (tiny images just meeting the bare minimum
ebay requirement, but insufficient for any real analysis).
You don't get sewing-machine type perfs (go away Jim

) on the Scott-listed perf. 8. This may be a sewing machine perf that HAPPENS to gauge 8 in one direction, but in my opinion that does not make it an R112c.
Frankly, I think the PF cert got it right as far as the Scott catalog number listed; it's the language they used in the description that causes confusion.
EDIT: If/when the item is resubmitted, we'll see what the PF actually changes on the cert. Until then, it's speculation as to what the intended verdict was.
