IMS’s B64-series competition basket — the 57mm-tamper series IMS makes
specifically for Lelit’s LELIT57 machines (the catalogue names the Anita,
Diana and Anna). This is the precision-basket upgrade path for the Lelit
Anna; the B70 (58/58.4mm) and B68 (Gaggia-fit) series do not fit these
machines. Verified against the official IMS product page and catalogue on
