Did any of these notes have a watermark?

I have one of these notes and there is no watermark:

Numista says it has a falcon's head watermark.

Is it a case that some of these have watermarks, or is the Numista entry wrong about the watermark?

Opinion based on observed fact of my 3 notes:

It can be seen in the main Numista scanned image: falcon's head. I scanned this one because it had the most visible “watermark”.

But the truth is, it's really not a watermark--it is a shaded image.

And some falcons are much lighter than others, if visible at all.

The quality control of Iraq notes in this era is shockingly poor. If you had 10 identical notes in hand, you may think you have 10 different varieties of color.

I hadn't noticed before: my note has that same falcon head outline on a regular scan. 

But nothing shows up under backlight. I also have a machine that can show watermarks without backlight, and nothing shows up there either.

Maybe the entry should be changed then, unless someone can show an actual watermark?

Yeah, definitely not a watermark if it is not the substrate density that forms the image.
