This are vintage manual coffee grinders presumably produced by an Italian manufacturer in around 1940s. Functionality: - Left grinder: the grinding mechanism works well. The grind setting from coarse to fine can be adjusted. Dimension: 40 x 12 x 12 cm. - Right grinder: the grinding mechanism still works, however there is a slight irregularity when turning the wheel. At some particular turnings the turning is not as smooth as the other turnings. This has some to do with the gears which have worn out a bit on some parts. But it still can grind coffee beans. The grind setting from coarse to fine can be adjusted. Dimension: 32 x 18 x 18 cm.
