External base from the Szigony Müszaki Vállalat business:
The invention was patented by Mr. Desider Stern (I am starting to like the man!).
He requested on the 19th of August 1946... 3 months before Mr. Giordano Robbiati requested the patent for his espresso coffee machine in Hungary.
These pictures i have made while visiting an exhibition on Coffee machines at the Hungarian Museum of Tourism and Industry in Budapest.
