Followed the instructions on my 320k to make one and it's fiddly and nowhere near as good as any straight stitcher with any Singer buttonholer. Got a 1960s version a few weeks ago that takes cams for different shaped holes (the green plastic box) and there's no reason this won't work on any of my VS2/27/66/201/FW. Just realised I have multiple machines for every one of those models!
Has anyone ever tried a SS buttonholer on a ZZ capable machine? I assumed it wouldn't work because they produced the "professional" meant for ZZ machines.
