My father bought me a cows knee for my traditions flintlock. it fits perfect on his TC but on mine the leather part that is locked down by the screw is not long enough to allow the knee to work correctly. Short of extending the leather on this one i cant get it to work. Does anyone make one specifically for this gun or do these tend to be 'one size fits all items? Is anyone aware of people who do custom ones? The one i have made out of leather is a little stiff...a softer leather may work better?
