But first a nice example:
Here are the Number/Holes combination i collected over time:
Mr. Imre Simon, head of the Szigony business, had a company book where he registered all the machines that left his shop. In this book, the number was associated with the date of purchase and name/address of the new owner.
Each machine has a unique combination. They can be considered as serial number.
A little story to this fact:
At the of the 1970s, As the 2 sons of Mr. Simon replaced him at the counter of the business for a week, considering taking over the business... only 2 persons came. What they wanted? A new seal... for a coffee machines that was made in the 1950s.
So where is this book?
and We'll never get the chance to crack the Szigony code...
