Parts for a 12 year old Munchkin 140M needed. (911)

Looking for a used mod. 140M. that could be parted out. I have a customer that inadvertently through away some parts off his 140 M Munchkin boiler. I need everything from the gas valve down to and including the burner door. He thought they were old, used no longer needed parts and tossed them in the trash. I had it apart so I could clean the heat exchanger the next day. Any help would be greatly appreciated.
