I am building a Lehigh Valley rifle using one of Dave Keck's pre-carved stocks (Stophil Long), and Rice Southern Classic barrel. I will be using one of Jim Chambers locks, but not sure which one would be the most historically correct, Deluxe Siler, Standard Large Siler, Golden Age Flintlock, or the Dale Johnson Flintlock. Could I please get some advice from you more experienced rifle builders? Thank you.
