The La Pavoni home lever espresso machine comes in a few models and all of the models are differentiated by manufacture date before or after year 2000. Machines made after 2000 are called Millennium and those made before 2000 are referred to as Pre-Millennium. This guide can be used for all models and manufacture dates. The main difference you will see is that Millennium models have a plastic liner in the group and the older models are simply brass. Take care not to score the brass or to break the plastic liner.
