AAT here, too
I have AAT 46xx, a 2 1/2" 19-5. Absolutely love this gun! There is something truly awe-inspiring that happens when I touch off a .357 in this baby. I find the recoil robust, but very manageable. It came with original service grips, and I added a Tyler-T. Fits my fat hand just fine, and is still very concealable. I find this set-up to work great, for me, and see no reason to put Goodyears on it.
As far as ship date, best guess, would be 1983 (as already stated, book doesn't list AAT). Maybe someone with a letter of authenticity or a correct box and end label, in the AAT range, can shed some light.
