Peter it appears to be several different kits that were used to make the diorama. The picture needs to be bigger to be able to see some of the details, this would make it easier to indentify the kits. Knowing what scale would also be a help.
Tyson,
thanks for your answer. So far I remember I have seen this model on the internetsite of a dealer. The dealer offered a second complete model with the scenery of a town in Mexican/Texas style. I don't remember the scale.
Regards,
Peter
