The owner of this rifle asked me to replace all the missing parts of the rifle that I could, ramrod, various screws and pins, etc. The last piece was the adjustment screw for the set triggers, missing in the photo below
Below are very similar triggers on another Ky made rifle, the John Clinkenbeard (attributed) rifle pictured on the KRF CD Volume XVII.
This screw was a challenge as it is a 5x48, but I found a die on ebay. My buddy Clockman turned down a steel rod to the right size for threading on his good lathe. And I shaped the head of the screw with files in my old worn out lathe. I think it looks ok.
