[CAUT] Friday Puzzler

I second Fred's advice.
You may need to do some carving on a few flanges, or wallow out the screw hole for clearance.
Given the overall condition of the action you describe, would it make any difference?

    I think it is indeed the screw holes in the rail.  For fun, I just screwed in the screws with no wippen on these 3 samples I took off.  Well, what do you know...the screws are at different heights!   

    Is there a way to remedy this, or am I stuck.  Is this a replaceable part?

  By "heights" I assume you mean with the stack seated on its "legs" (normal position), facing the wippen rail, you can see that the screws are out of line with one another (up and down relative to a straightedge anog the rail). What you would expect if the screw holes were either not in a straight line, or drilled at varying angles. Is this what you are seeing? If so, it sounds familiar (I have a number of 1960s S&S grands with badly drilled rails).
  Yes, you can replace the rail (or have it replaced). But I'm not sure that is necessary, especially for a wippen rail on an M. I would simply find the worst ones (up and down) and deal with them individually. Place a shim (sticky paper, like for travel) on the bottom of the flange in a right angle alignment - in line with the row of screw holes -  at the front or back of the flange depending which way you want it to tilt to account for the screw hole problem. Meaning the paper is in one of the curved parts of the flange bottom. See if that is enough (maybe two thicknesses). I have found I often needed to relieve the top of the flange at an angle so the screw top didn't overcome the effect of the paper.
  I have never bothered with the wipp rail, just the hammer rail. I'm not sure the effects are enough to be worth the trouble, in a practical world.
