Mark - I did receive your pictures of the Krag carbine and the Remington 1903A3. They can be downloaded and viewed, but, not altered on my computer.

FWIW - Actually, Federal law allows rifle barrels to be as short as 16 inches, now. Shotgun barrels still have to be 18 inches long.

Your Remington 1903A3 appears to have been cut-down for 'Hunting'. The work was neatly done, but, not official government work. If it were mine, I would have a replacement, full length, surplus 1903A3 barrel put on it and stretch the stock. (If the barrel is 16 inches long, measured from the muzzle to the closed bolt-face, it is legal).

Too bad about the alterations to your model 1896 carbine stock. (Thank you, Dick Hosmer, for kindly posting Mark's pictures). The metal appears quite nice.
