Here's what JC writes about 27798 on his site:
"The pocket position is also interesting, as Dubow would often position them with even spacing from the cut edge of the wind flap, not the zipper."
And that's about last Dubow's 1755:
"Dubow's last A-2 contract dates to late 1943. They have the same pattern as earlier Dubow A-2 contracts (23379, 27798) with the simple collar design, and have pockets centered by the zipper, unlike some earlier Dubows which have imbalanced pocket position (the wind flap pocket tends to be much closer to the vertical seam of the body)."
So, it looks like both options (zipper centered or windflap centered pockets) are correct for original Dubow A-2's, it actually depends on specific contracts.
P.S. Juanito, congrats with your very nice purchase! Very like this jacket!
