As some one mentioned, Lee Six and Chet Brown were partners. After a short time, they split the molds and went their separate ways. I bought several stocks from Lee. They were a much better made stock than Brown's but required more work than today's stocks. He made both benchrest and hunting rifle stocks and was a great supporter of benchrest. In the mid-eighties he started making the injection molded stocks as used by Remington and others. One shouldn't hold this against him! The Lee Six stock business was sold to George Kelbly and the last Six stock I bought came from there.
I still have and use two Lee Six BR stocks I bought in 1978. GD
