## Notes

La Marzocco's convertible portafilter — one body that swaps between single-
spout, double-spout and bottomless. La Marzocco states it is "Compatible with
all La Marzocco Home machines along with standard 58mm tampers," so it is
cross-referenced to the Linea Mini, Linea Micra and GS3. As a 58mm
commercial-standard portafilter it takes standard 58mm baskets. Verified
