I believe the FW has a small attachment cover plate to go over the feed dogs for FMQ and darning. They really are cute machines, but the harp is so small that you can't stuff much volume in there when quilting. I would recommend that you check out the 301 - a little bigger and the feed dogs will lower. I have both a 221 and a 301, and I prefer the 301. It has a needle plate that is marked for seam allowances including the 1/4".
Enjoy learning about the FW and other vintage machines!
