I guess your are right .. Although they do look rather improvised. . .probably a limited order placed at some factory somewhere. ..

And btw. . I used to live in a Communist country.. and EVERYTHING that is not for export is more or less improvised or rough.
It usually does not take a whole lot of licensing to have that sort of business and the employees are a group of semi skilled craftsmen from some remote village that rarely gets attention from the authorities. .

The best word to describe almost everything in a communist country, including the exports in many cases ( Made in China ), is "shoddy".
