Rövid történeti áttekintés a magyar svájcisapka

"Rövid történeti áttekintés a magyar svájcisapka", or: A short history of the Hungarian beret.

Indeed, it is a very short history, but I am still working on it (and any help would be much appreciated!).
It was in 1889 that "Kokron" was founded by Joseph Kokron in Hódmezővásárhely (in the South East of Hungary). 

During the 1930's Joseph began the production of his special berets, with specific Hungarian developed and patented technology. Nor-Coc was chosen as a brand name and these berets were extremely popular in Hungary and abroad. production discontinued in the 1960's.

I have found some interesting advertising material of the time and also photographs of berets with Hungarian labels (see pictures) - whether these are Nor-Cocs, I don't know.
