Vintage Berkel Europe Model 7 Blue Slicer: History, Specs & Restoration

The Berkel Model 7 flywheel slicer is one of the most iconic vintage food preparation machines ever produced. Manufactured between 1922 and 1928, the Model 7 represents the second major model assembled directly in the Italian factories under Van Berkel's Patent Italy.

Evolved as a specialized variant of the legendary Berkel Model 5, the Model 7 features a redesigned open clamping arm facing the flywheel, allowing operators to secure longer products much faster. While classic models came in red, black, and ivory, rare custom editions—such as the Berkel Model 7 Blue—remain highly prized among international collectors.

• Second Series International: Upgraded to a larger 370 mm blade and a 394 mm flywheel with the official Rotterdam marking.
