I have a couple of the tuckers like the one in the picture (center right, looks spring loaded) that came in the drawer of my 1886 Singer Improved Family. My ruffler is different, probably since it's later. I also found on of those long bobbins, even though the IF is Singer's first round bobbin machine. I'm just curious about the two needle plates next to the bobbins, since mine came with a couple of extra, too. They look the same, so why would you need multiples?
