[pianotech] Mason and Hamlin parts?

[John Ross]

Cast iron can be braized, I think that is the right word. They used a brass welding rod.
I just had a broken pedal repaired.
A good welding shop, should have no problem.

  Dale Probst, Registered Piano Technician suggested that I would be better
  served by posting my question to the pianotech list.

  My question:

  I am just learning about pianos. I recently purchased a Hamlin and Mason
  piano Model B manufactured in 1940 per the serial number B50186.  Tracking a
  squeaky "sustain" pedal has lead me to the underbelly. The cast iron
  assembly (part # s696) supports three rocker arms (part #s s693, s694,
  s695).  The movement of rocker arm part # s693  is sloppy and the source 
  of the squeak. The metal area around the rocker arm and pin shows signs of 
  cracks and previous repair (including a pin larger than the others). Being cast iron, I
  am told that welding is a very unlikely solution to repair the assembly.  Is
  part replacement my next step?  Where can I find parts? Thank you.  Dan
