The original image is not perfectly horizontally straight, it is rotated to the right by 0.03 degrees. Here is the original image rotated to the left by 0.03 degrees and then two identical horizontal lines added for reference.
To my hobbyist, non-expert eye and based solely upon the image…
The top and bottom perfs both appear slightly angled (compared to the stamp design) but they are angled in parallel. Additionally the top/bottom perf alignment looked ok when I did the Srail test.
They do look a bit wanky but I was about to say I think the stamp is ok but then I saw the asking price of this listing. (Also choked on the 'LH'.) Best to wait until someone like Clark offers his opinion on a stamp that pricy!
