Thirties kitchenary

Such a cool ánd handy cutie this 1930s scale is. I purchased her at the most remarkable place. A biological farm we went to for free range eggs. I love going to those places to buy fresh eggs, karnemelk, meat ect.. And to cuddle with the cute animals of course... But this was the biggest surprise of the day; it turned out there was a little vintage kitchenary shop on the property as well. This adorable scale is still functioning very well and only cost me 5 euros! (L) After hitting Google I discovered she's probably from the thrities and made by the Swiss. But if you can tell me more about these darling scales; please do!
