I would not be surprised if every D grade and most C grades were made to order to a large extent. By that I mean if you contacted them to build you such a gun they would have made the barrels 28, 30, or 32". Now convention for 10 ga. might have been 30 or 32 but a 28" should have been available upon request. Since I have no 28" I have no way to tell but will gladly accept all free Remington 1894's as others wish to send me.
