Here's what I could do.
Based on the logic that the back measurement of size 40 jacket is 25 inches, then size 44 is 27 inches as Mal says. I believe that the theory that TOD was 1 icnh longer than Raiders does not stand. When I scale the NH jacket to measure from collar seam to bottom 25 inches, then pocket size corresponds to 6 x 5.5 inches. When scale it to 26 inches back, pocket size changes.
So what I did was to enlarge NH jacket so that back measurement is 27 inches. The pocket size changed as in the photo below.
I repeated same technique with Mal's jacket and result is pretty close.
So, I would suggest pocket size for 44 size jacket to be 6.5 height x 6 width. The pocket placement should also change according to the NH photo example.
Here's the photos
Mal, another way to test if this is right is to cut two pieces of paper with dimensions 6.5 x 6 inches and place them on top of the pockets of your jacket to see how it will look.
One other suggestion is to sew Raiders pockets on the jacket and make it a Raiders jacket.
Anyhow, here's a drawing showing old pockets (black) and where the new pockets could be placed (red). As you can see, they cover the old stitching quit well I believe.
Hope it helps
