Gentlemens:
I have talked to these folks about the action and they seem sincere in their efforts to produce it. They say that it is an accurate reproduction and the parts will interchange with originals. The exception to that is the Mann-Niedner firing pin they used. (If there ever was a solution out looking for a problem, it is the M-N firing pin... but I digress)
It is their intention, as relayed to me, to provide the action in a number of configurations in the future, including all of the set trigger variations. They now have examples of all three set triggers to reverse engineer.
I have no dog in this fight except for our collective desire to have another source for Winchester actions and parts. I wish them well. They did mention a while back that they will be at the Guild show in Reno at the end of the month. If so perhaps more detailed and current information will be available.
