Paradox, I own a model 1903 (dated 1926) with 23-inch barrel and full stock; I posted it on the Forum once but I assume photos are now gone. The rifle is in mint condition, the barrel (intermediate between light and heavy) looks to be original as well as the stock (serial number stamped into). I assume that special orders were possible from Mannlicher Schoenauer as outlined by Rothhammer1 as this case, although not common, is not rare.
