I, too, am a shooter, not a collector. It's been my experience that there are many early (pre WWII) American doubles, especially Ithacas, that are stocked with "modern" dimensions. The last one I purchased was a Flues field grade, with drop of 1 3/8 X 2 (original). I also have a Smith Specialty with damascus barrels, original stock, 1917 mfr that measures 1 3/8 X 2 1/4. This gun may have been special ordered, but I'm sure the Ithaca wasn't. I believe what you want is out there, you just have to be willing to look and wait for it to come along.
