Interested in seeing the trailer in production if you have pictures

Apologies Frantal, I checked my photo archive and it seems I did not keep a record of this construction. If you have a question about a particular method or detail I am sure I will have an answer for you.

Sounds like wiking with a homemade roof? and bravo for the removable rear staircase

It is a Herpa model, It is no longer in production....It came with a removable roof but I added a layer of styrene to alter its appearance and the stairs were simple construction from Evergreen strip styrene with common pins for its axels.

thank you and well done

Here is a conversion of the Bussing 8000 into the Bussing-Nag 900 with the "rare" sleeper cabin....

And here is the completed project.
