Are these Renner parts? The shank/flange seems to be? If so, the spread should be 113 mm. Did you say that it was either 110 or 111? That would place the drop screw in a better position and increase the jack clearance. That can be achieved by shimming the wippen flange. With properly regulated dip and aftertouch, the jack should never get to the position shown. It should clear the knuckle only fractionally. That's my initial thought.

I may have to do multiple emails though so it passes through the filters in a timely fashion. Here's the first showing direct manipulation of the wippen. Note where the drop screw contacts the leather. The jack tip is contacting the hammer flange in between the hammer shank ears. More to follow.

The jack/hammerflange contact is not unheard of. Your problem is more likely in the rails than the parts. If the hammerflange rail is just slightly rotated, there is interference. The pin to pin distance may be correct, but the flange will be out of place. Ususally when this happens, the drop screws are turned all the way up. If no new parts are available, you can often stop the problem by removing the proximal half of the jack, near the top.
