Jack: The ludwig that I regulated had the Thayer action according to your discription. I thought that I got the model number but I guess not. Sorry.

  Hello Tom.

     The action you describe  sounds like the one
  developed by the  Thayer Action Co. for M. Schultz.
     
      If so the spring you describe  will make a half 
  circle.  One end will hook to a round shank glued 
  into the main whippen lever.

     Such an action  model is in the  PTG  Museum.
  Also one by  W. P. Haines  that is similar  except 
  it has an adjustable but weird spring that is 
  supposed to act as repetition lever

    To regulate this action is the same as an upright
  with the shank resting on the hammer rail.

     As a side note,  Ludwig built a Grand piano
  with the main cabinet made of concrete.  Please
  check this case I would like to have this Ser. No. 
  Regards to all,
  Jack Wyatt
