Replacing shot-out and rusted out barrels was very common in the era of black powder and corrosive primers, and many guns of that era have mis-matched barrels. (I recently saw a post about a Stevens rifle with a Remington 510 barrel - same thing.)
Further note for Tom: The front sights are easily made. Contrary to what is commonly believed, they were not soldered or welded in, they were just press fitted, using a specially shaped arbor press head to prevent them being bent or damaged in installation. In replacement, installation is usually with a vise, using brass or lead jaws to prevent damage to the sight.
