Present regulation is very good.  It is Renner action with smallish Renner hammers which I am sure are original. The action ratio is in the 5.5 range.  It has to be said that I intend  taking the action apart and check out all the centering and any key friction, and I expect this to make the touch more even.  That said,  I still appear to have a fundamental problem which I will need to be addressed, and I am asking for comments and ideas on how to approach this. Don't hold back!   ric </div> </body> </html>
