This instrument needs a normal Steinway regulation.
With normal I mean that Steinway has  Steinway specifications, weights and
measures for every part and every regulation procedure like:
Key dip - hammer alignment - hammer travel - hammer spacing -  let off -
hammer drop - back check - springs - hammer blow - key frame, and all the
numerous other things we have to do in order to make a beautiful touch and
tone.
Again, to obtain these data one should buy the Steinway manual. If one doesn
't, then it is like trying to drive a car without  driving lessons, usually
resulting in a car accident and possibly a wreck.
Now to answer your specific question about Steinway key dip : on models S
through B, key dip is set at 9,5 mm. On models C and D the key dip is 9.75
mm.
