Hello Phil: Sorry to be slow in my answer to you. There are two of these actions, the first has a very complicated let-off system. The second had a let off system that we find on the average action. The second works as well as the first. The top of the ether jack forms a -- Y --. And the regulation are the same in that area. This is where you regulate the check. The rest is standard settings blow distance, key-depth ect.ect. However this action has very little after touch feel, if any. So don't expect any. If you have the first action with the complicated let off system be careful when turning the regulation screws. You may very well have to heat them before they will turn. I have parts for this action if you need them. If you have the first action please phone me. My shop number is 972 - 278 - 9312. I will be using my "Staib model" in a new class in Chicago. " Laying Touch In The Upright" Hope this helps, Jack Wyatt
