Can't help you with your question, but I have some interesting Knight trivia that Clark will probably appreciate as well.
I just returned from our annual trip, hunting for 7 days near Lancaster, Missouri. Tony Knight started his business there in a small pole barn just east of downtown on Hwy 136. My father met Tony there in 1987 as he wanted to combine a turkey hunting trip with a tour of the Knight facility. After the inline design proved viable, Tony wanted to expand his business but couldn't get the local government to agree on some tax issues. He decided to move the facility across the state line to nearby Centerville, Iowa, some 25 miles away, where I believe it remains to this day.
Dad ended up meeting some other local folks and we still hunt in the Lancaster area, 20 years later. Every year he still points out the building where the inline muzzle loader had it's humble beginnings. I find the history interesting, hope you do too.
