Some of the Kenmore 158-xxxxxxx series uses that type of button holler. You remove the bobbin cover plate, instal the button holler drive plate and then put the button holler on. There is basically two versions of this that I know of. The flat bed which is what is on the eBay site, and the free arm type. The drive unit is the difference, the button holler itself it the same.
They are very easy to use. Much better than the built in button hollers modern machines have.
