Axel Peterson was a Swedish immigrant who became a very respected gunsmith in the Denver area in the late 1800s, and whose shop remained in business until World War 2. Peterson was best known for his smallbore .22 target rifles, but he did much more than just that. Like, for example, this .22 rimfire single shot Luger conversion. This is a really remarkably complex way to make such a pistol, which makes it all the more interesting to look at!
