For sizing A-2s, the general rule of thumb is that you go with the chest measurement, rounding up to the closest size (in this case, 44), and then go up an additional size. You should probably go for either a 44 or a 46, depending on how fitted you want the jacket to be when you get it.
Mostly shrink. Most tanneries, including Victoria, the source for Platon's leather, stretch their horsehide as part of the tanning process (in order to get more bang for their buck). As soon as your jacket gets hit by a decent rain storm, it'll shrink up a bit. My experience has been that you'll lose an inch from the chest measurement, and about half an inch from the other measurements. For this reason, from your description of your measurements, I'd be inclined to advise you to order a 46. A 44 might work too though. It all depends on whether you want to start out with 4" of breathing room and end up with 3", or start with 6" and end up with 5".
Also and I apologize for the silly question but how does A-2s normally behave in time. Do they rather have a tendency to shrink or to expand morphing on the owner's shape?
