https://rocket-espresso.com/pdf/ROCKET_Domestic_Catalog.pdf (archived) — Official Rocket Espresso domestic catalogue, read firsthand 2026-07-15. The Porta Via page states verbatim: 'With PID temperature control and E61 brew group, you get precision extraction and steam performance wherever your day takes you.' The catalogue prints no portafilter diameter — the 58mm figure follows from the E61 group, which is a fixed 58mm standard.
https://www.imsfiltri.com/IMS-competition-Catalogue.pdf (archived) — Official IMS catalogue, read firsthand 2026-07-04: IMS's 'For tamper 58 / 58.4' B70 basket compatibility list names ROCKET — third-party manufacturer corroboration that Rocket's E61 machines take the 58mm standard.
