Scott 1041, 1041B, And 1042. Did I Get These Right?

IBFS: Yes, the difference does appear rather dramatic. But the ratio of the two heights is about what one should expect. I zoomed in until the stamps were approximately 5 times the specified height. I then carefully measured the heights of the two stamps on the screen with a metric ruler. What I got was 106mm vs. 105mm ... the difference ... 1mm ... 5 times the 0.2mm of the actual stamps. So while the apparent difference might appear too great to be correct, math tells me otherwise. I do agree, though, that the apparent difference appears a bit more than a single line of engraving. That remains true just looking at the stamps with no magnification. Unfortunately, I only have the single used copy of 1041 with which to make comparisons. Maybe I'll invest in a couple of plate blocks & take a closer look at them. I do need a mint copy of 1041 anyway. Thought I had one & was quite surprised to find that I did not.

I thought I'd try my hand at attempting to identify the 1041 and 1041B varieties from my stockbook. Although these aren't the greatest examples, do you think I have identified them correctly?

They look correct to me.

Then I'm confused about what Scott says, and whether or not I have the right stamps.

What I find strange is that Scott identifies the design as being 22.7 vs 22.9 mm. I don't know if a .2 mm change would be visible to the naked eye easily. Now, from the pics people have posted, the overall size of the stamp seems to be taller, and I think it's taller than just a 0.2mm difference. I wonder why they didn't use the overall dimensions of the stamp for identification.

Ok...

Went back to the stamp store. The owner had 1041 and 1041B stamps, which he had identified by breaking up plate blocks. We took my stamp and stacked it up against a 1041 and 1041B. The stamp was the exact same size as a 1041. So, then I bought a 1041B off of him, and we put the two side by side. Sure enough, you can spot the difference with the naked eye.

When one stamp is wet flat plate printed and the other is wet rotary press printed, then it is easier to tell them apart by design measurement differences. However, this becomes much more difficult such as for the above stamps when one stamp is dry flat plate printed and the other is dry rotary press printed.
