On the outside, this grinder is very similar to the Nuova Simonelli MDX grinder. While in a resturaunt today, I saw two of these and inspected them closely as to tell how similar the photo is. However, the MDX do not have the tamping device shown but rather only the usual plastic tamping attachment. The MDX is a typical flat burr grinder with a flat burr diameter of 64mm.
Italsab manufacture a superauto and rebadge other's traditional machines and grinders. The grinder shown is a Eureka MDM, which is also sold by NS and other manufacturers. Eureka (Conti Valerio) is an old line and well reputed grinder manufacturer.
