At some point in time all of our impressions break down, even at the most absurd levels. We live in the here and now and can't get away from it. One has a hand forged barrel? Was that iron ore dug by hand, wrot out with hammer and forge? Was the smith wearing hand sewn linen and wool? Where did he get the wool. Eighteenth century sheep don't exist anymore. Did he eat pork in his meal, those pigs aren't around any more.
You can get parts that look like modern parts, and plans for a gun of that type. So you can make a reasonabl copy for the same price as a generic gun. However one might want to make some changes for our wold today that was not done back then. Many southern guns had very thick barrels to a small caliber however we migh choose to keep the barrel size but have a larger caliber for our needs today. IMHO this does not impact the impression.
