Large Model Rail Cars

I need your help.

Are you a model railroader? What brand / model are these cars? I have others like them.

These are BIG cars. Think garden railroad. Look at the tape measure in some of the photos to see how long they are.

They fit PERFECTLY on the large Buddy L track that's got an inner gauge of 3 and 1/8 inches.

This is the track that looks like REAL railroad track - the same profile.

Can you leave a comment below or a URL to any site you discover that can help me positively identify these cars?

I contacted the Buddy L museum and they said they are NOT Buddy L rolling stock.
