Is there a track for 39-408?

The 39-408 is a very old style operator and I don't believe too many parts once associated with it are still available. If you could, send us some photos of the operator you have along with any other parts that are related to it, especially the track. This could help us recommend what parts you need, or at the very least a working substitute.
