A few facts about the machine

Built in 2016, the machine was designated by the parent company as an exhibition model for trade fairs in Italy during 2017. It has been installed for the first time at the current user place (sole owner) during 2018. From 2018 to date the machine has worked very little, about 2700 hours. The steady rest (full axe) supplied with the machine is still packed in its original packaging and it has never been used.
