Height also looks greater than the 581. All this talk about rotary vs.flat plate and perf 11 made me go back to my US album and check my flat plate perf 11s (Scott 551+). About half of them I had misidentified (actually rotary press ones)

Am working on uploading a different shot now with the right image. On here it does look off, however I think that is due to angle... will send the "directly above" shot we have that lines up all the way.
Because you posted a camera pic and not a scan, I cannot directly compare the 2 stamps because of issues with the slight camera angle (if you compare the 2cm spacing arrows, you will see that the right side is slightly closer to the camera than the left side).
However, I can tell you...
mdroth is correct. The stamp at right, the left side is perf 10½, not perf 11. I cannot check the other 3 sides accurately because of the slight camera angle. I would "guess" you have a common #632, which is perf 11x10½.
The stamp at left is perf 10 at the left side. Again, I cannot check the other 3 sides, but it does look like perf 10 all around, so it is probably the common #581 (perf 10) that we wanted for comparison.
You are using your perf gauge incorrectly when you tried to measure the perf 11. Your perforation is a non-continuous gauge, even though it puts perf 10, 10½, 11... in sequence on the side. You need to line up a complete perforation hole onto the first complete perforation hole that is inside the start/end arrow. I can't tell if you tried to align it in the middle, or maybe onto the a partial tooth/hole next to the arrow, but either way, your stamp is not placed correctly to measure perf 11. Later, I'll post a picture of your pic and then a shifted stamp pic to show how the stamp should have been positioned.
Hi KHJ, The first 4 images are from the scanner. The last few, from the camera. I Used the first complete hole to line up the perf gauge. I do greatly appreciate the information letting me know what it is Saves me a bundle getting it checked out "officially" Thanks again to you too mdroth. Hehehe.. My wife is still insisting its an 11... I will go back over all information with her here. Thanks again
I was only using two of the pics with the perf guage, which appear to be camera pics.
Here is an explanation of the correct stamp alignment for your specific perforation gauge type. In your pic, the full hole at the left is too far to the left, making the right-most holes look like they almost fit (or, you could say the first full hole at the right is too far to the right, making the left-most holes look like they almost fit). Shift it correctly (either direction), then you can see there is clearly a half-hole difference between the perf 11 marks and the actual teeth/hole of your stamp left side.
Actually, the reason I was using the perf gauge pics was to show the proper way to align the stamps using that gauge.
Your earlier stamp scan was sufficient to prove you did not have a #596. In the picture below, I have isolated the single stamp in question from one of your scanned stamp images, rotated it slightly to get it closer to standard axes, and then copied/pasted/rotated the bottom side to put it next to the right side. You can see a clear half-perf difference. Listing out all the perf possibilities, by process of elimination it can only be perf 11x10½ -- don't need a perf gauge. Since the perfs don't appear to be altered in any way, that means your stamp must be a Scott US #632.
While I'm grateful I can now do a lot of these manipulations on computer, I have to admit that it's rather discouraging that I can no longer do this with just my eyes, the stamp, and a gauge. They say the mind is the first to go, but for me it's my eyes (although my wife might present the argument that my mind went long ago... ).
