Of the Hawken rifle shop.
While they didn't keep the best of records, it is widely acknowledged in these circles that Jacob and Samual Hawken first officially opened up shop and began their rifle manufacturing business in St. Louis in 1823.
The gentleman in this video has built a rifle commemorating that anniversary. He has utilized authentic Hawken parts from The Hawken Shop. Many of these parts are still being manufactured on the same tooling, utilizing the same methods employed by the brothers Hawken when they first opened their shop. Samual continued to develop these rifles after Jacob's death in 1849. This rifle, like mine, represents Samual's ultimate development of this rifle.
You'll notice a lot of similarity between this rifle and mine. We used the same parts, so that should be expected. This one is far more ornate, as a commemorative probably should be, but it's really not in keeping with the "working" rifles produced by The Hawken Rifle Company. Very pretty rifle, though.
My rifle, just for sake of comparison:
