David, Good advice all. I'll have more time to play with it this weekend. I hope. Anyway many thanks to you and to Ed and to everyone else for all your help. Much appreciated.

I suppose proximal and distal is a more accurate way to describe things if I only knew what they meant :-). I wonder if they aren't Hamburg parts from Steinway. The current Renner doesn't have the buckskin wrap but it's possible that the ones that Steinway provides do. It's been awhile since I order them that way. The rails may not be in the right place (wouldn't be the first time) which would explain why you are having trouble with parts alignment using the Renner kit as well. I would still try to work the spread out to 113 mm (via the wippen flange) on one sample and see where the drop screw falls on the balancier leather and while you're at it also whether the jack, when aligned properly to the knuckle, aligns at 90 degrees to the shank. One other consideration, it seems to me that a hard blow shouldn't cause that much difference in the jack escapement unless the front rail punching is too soft. Consider a firmer punching (maybe Wurzen felt from Jurgen) and see what happens.

I was thinking of the front as the front of the action ... key area. I suspect that I might need to shim both the hammer side of the hammer flanges and the top of the wippen flanges. That should give enough clearance but how did it ever get this way in the first place? Is it rotation of the rails prior to soldering or is the spread between the rails wrong or what? Wrong parts? If so why doesn't anything from the Renner parts kit work? Weird!

Won't that make the jack contact even earlier? I know I'm missing something here.

I've forgotten the numbers but remember these are Steinway parts.

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.
