This is a quick demonstration and test of a 1950s KyM model 9401, in beech and walnut. 679 was the pre-war number for this model, and by the 1950s the model had been updated, and was given a new four-digit model number. Sadly I did not have this information when I recorded the video!

Feel free to look at my other grinder videos, may your grinds be consistent and fine!
