This question about the pencil numbers couldn't have been asked in a better moment: i have a meeting pending with Mr. T.Simon, one son of Imre Simon.
This picture - the inside of the head of a Szigony/Qualital coffee machine - was contributed by an australian collector... who is apparently trying his best to refrain me putting an endpoint to this Blog.
Another humbling reminder how much i don't know about these machines...
... humbling & always exciting!
The "311" is for sure the production number.
If you have other questions... just write me an email, or comment on this post!
