Maybe the S stamping was applied to a counterfeit Hawken??In John Baird's book "Hawken Rifles" on page 21 there is a photo of a well worn J&S Hawken stamp on a rifle. No "S". On page 25 there is a photo of a lock plate with J&S Hawken on it. This leads me to believe they never put an S on the end of their name.
