I think if I remember the Papoose was bu7ilt5 by an american company called Bowlus Teller Trailers. They date back to the 1930s.
If its the ones I am thinking of they look a bit like the Airstream caravans, this was due to the fact that William Hawley Bowlus one of the founders of the company had a long career in aviation, building sailplanes and guliders.
