Parts source needed. Newbie questions.

[CC25]

Hello Everyone, 

Thank you for allowing me to join the group.

I don't sew but have an Amish friend needed parts source for a Mitsubishi LU-400 BOB machine.  I was able to find a schematic for the machine, but the two "known sources" (known to the Amish guy) for parts are unable to provide them.  The parts needed are associated with the walking foot, and parts to add an edge binding attachment.  As you can imagine, being Amish without a internet, a telephone, even a computer, the struggle is real.. 

Is there a truly "go to" supplier that would have a catalog for this particular machine?  Again, I'm not the one behind the machine, just a friend with an internet connection.  Thanks in advance!
