I have had a couple Turissa machines for years. I've never really used them though. I bought them because I liked the look and that is was Swiss. I have a greenone that takes cams and a tan one that doesn't. I've been looking far cams for a long time. At some time Turissa was taken over by Gritzner-Kayser in Germany. I've neer been able to find out if the design was theirs to begin with or if they took the Turissa design and ran with it. Some time ago I found that the cams (which are impossible to find for Turissa) are actually the same one used in Gritzners of the time. And Gritzner made the Kenmore 117-840 and 841 as well a one of the White machines. i can't remember which model. So for a long time I have been looking for cams for any of these machines. Well, the reason I am on here today is because I found a full set for Kenmore on Ebay today and bought them.Now I just need a manual so I know how to use them. lol. Mick
