From this poor seal image, and from you bird images. I'll go along with the bird in the seal but looking at your bird images, what you think is Coo is in fact that rope pattern branch the bird is stood on like the birds in your pictures.
The OO is one an oval O split with a crack in the seal.
Hello All
dobfarm, I think the second letter O has a crack through it.
Between the birds legs I don't feel it is rope, but some type of calipers, or divider/pincer, or other instrument, if you go back to my improved image (not the one sketched over) of the Red Seal, this detail seems to have been more protected by the border.

the left leg has its claw folded over the instrument and
the right claw stood on the edge of the instrument
I'm waiting for a close-up photo, I also want to see what lettering you and others have noticed in the border / bordure.
Altering the seal indicated a different generation from the last.
I am very much picking this up as I go along.
