i sent one of my Spectrum 2-8-0s away for a sound decoder installation.
It came back with both pilot and tender couplers missing and one of the pilot wheel journals broken so the pilot truck axle is only held in place by one journal.
Can Bachmann couplers and and now pilot truck be ordered from Bachmann?
Bachmann or Kadee couplers should fit. Pilot wheel:

I would contact the person who worked on it and ask what's he going to do about it. Joe
