foufymaus, Sears sold a lot of machines under the Kenmore name, made by many different companies. So you need to figure out which manufacturer made the machine your attachments fit.
Also - there is a set for flat bed and a slightly different set for open arm machines too.
Share a picture of the attachments you have, and maybe we can help you with it.
The one on the left fits the flat bed 158 series (at least the later models, not sure about earlier ones) and though I don't know for sure, I think the one on the right is for an open arm machine.
The left unit has a seperate box with all the templates in it. It was a four box set my series Kenmore, (I may not have the titles correct though) Attachments and Mongrammer, Accessories and buttonholer, Monogram Templates, and Decorative stitch cams. If you have the box that says "Monogrammer and Cams" I have only seen that in the Open Arm style.
The throat plate is removed, and the monogrammer, OR the plate with drive gear for the bottonholer is attached, so you have to match up the unit with a machine with the correct plate.
