Here is a .58 fullstock flint Hawken that I "aged" on an elk hunt.
When I no longer had the muscles to shoot this off-hand in our matches, I sold it. I had maybe 1500 rounds through it. Taylor Sapergia, acting as agent, bought it for Hatchet Jack up in British Columbia. Hatchet Jack wrote me December 18th and he now has 9000 rounds through it. I'd bet it doesn't look much different than when I had it. Here is Hatchet Jack with a halfstock flint .50 caliber Hawken type rifle built by Taylor.
As of December 18, Hatchet Jack had put 22,225 rounds through it. It doesn't look much worn. So good luck to those putting their own wear and patina on a rifle. It won't have changed much when it goes into your estate sale. Here are five of my Hawkens.
I aged the Bridger rifle (third down) because I know what it looks like now, and I like it. I have shot this maybe 1500 to 2000 rounds, and hunted deer and elk with it. The fourth rifle is a .58 flint Hawken style, and I killed a mule deer with it. The bottom rifle is a .50 antelope rifle, aged because I wanted that look. I killed an antelope with it and shot it maybe 300 times and gave it to my nephew, where it will be an heirloom. The others look new, I had no reason to age them.
