If you examine it under a USB microscope (or a 20x-30x power loupe) my bet is you will find that the black is on top of the purple company cancel rather than underneath as it would be on a legit overprint.

Is looking at it under a microscope the only way to determine it's fake?

I've found that scanning it and making a jpeg usually works well. You can then blow it up and use the various filters to clearly see what is over/under what. Hue and saturation along with contrast and brightness usually make it evident.

I don't understand the question. Doesn't the document you posted give you that information?

@usrevenues: I believe USAFE7 is asking for facts he might have missed or are not apparent on the document or stamps (correct me if I am wrong David). Other than that, just general comments.

On the image provided, it is easy to see that the fake "IR" overprint is written on top of the cancel. This could be seen also using a magnifying glass. Of course, using higher magnifications gets you better resolutions (up to a point).
Is your industrial microscope by any chance a stereo scope with twin eyepieces? If it is,
do you think it has a greater advantage at identifying some of these things you are so
good at finding?
I used a stereo microscope for identifying defective parts as a manufacturing engineer
and found that you can see important details, that would be impossible otherwise! I
have often thought of getting one again to use for stamps, but not sure if it would be
worth the extra expense.
