There used to be an Oldenburg Antique Firearms in Oldenburg, Franklin County, Indiana. I frequented it when I was a teen and young man. Don't know if it's still there, as I moved away seventeen years ago ... but anybody in Oldenburg could tell you. I have "googled" it, and found nothing, so they don't have a website, if they're still open. They used to carry a number of handmade rifles in a time when there weren't that many of them around, so if they're still active, I expect that they probably do traditional.
