Wagon does not fit Horses as it is too wide, Upon google image searches the Wagon may or may have not had several horses connected to it. And these two horses would have had a different wagon and the two people and dog may have been pieces to both of this and the other missing units.
Some where someone else either has a miss matched set to these Or they got lost and these are the remains.
I just got these so I don't know anything else about them.
Would like $25 for them.
