Beginning this month, the GB5 2 group models (serial number 4978) will be produced with shiny stainless steel exterior panels in place of satin stainless steel. Shortly, the same transition will take place on the 3 and 4 group models. La Marzocco’s decision to eliminate satin stainless steel from production is principally based on improved quality and durability of the grain of shiny stainless steel.
