If I'm right it is there, but I did not fully understand the context (as in what it means for expendable net income).
Just found a reference to net (as in after taxes) salaries in the Netherlands in the early seventies(yet unable to find references for the fifties)....a whopping 305 guilders a month
that would make a faemina a high income toy for sure!
To me it helps using my pre Euro currency as I can better relate that to other historical prices here.
With the currency calculator I found out that a Faemina would likely have cost 286 guilders in 1955, which is IF the price would be the same because in those days import duties etc were surely affecting prices outside Italy.
just shows me that in home Espresso likely always has been something for those in the higher income brackets, I do not see workers with an average income after taxes of approx 300 taking out 286 for an Espresso machine.
As a reference, Some time ago I picked up a beautiful bakelite tube radio from 1955, that one did cost a whopping 245 guilders....also a high income toy I guess....
