The tent you are looking at are standard German scout tents. Each scout carries a panel and when they reach the destination for camp they put the pieces together.
These tents are called ‘khote’ and are based on the shape and function of the Saami tipi-like reindeer skin tent. The Saami (sometimes called Laplanders) are the indigenous people of Sápmi, which today encompasses parts of northern Sweden, Norway, Finland and the Kola Peninsula of Russia. (Ref. wikipedia)
Eberhard Koebel developed a design that incorporates several smaller canvas panels that are carried by individual scout as and assembled when they reach the campsite.
The panels are available in different sizes and configurations that can be assembled in many different ways.
Die-Kohte features some pictures and history (link to translated site)
|Fahrtenbedarf sells the individual panels and complete kohten|
A lot of information about the German black tents you can find on http://www.jurtenland.de there are some information in English and French too.
Here are some pictures about the “jurte” I colected on the net:
I hope my group can manage to have one of these tents in a near future.
