I have not teased,I do not know how it works,there is no instructions.the original box is in condition 6-10,as it is very old,and damaged as photos show.The coffee grain holder mates up correctly with the dispenser,the coffee holder with the black handle is stained around the hinge.Both black handles are in good condition,thanks for looking,I believe this coffee maker is around 1950s,no major faults to report..Well made in Italy.I am unsure of the type of coffee it makes.thanks for looking.
