OK, I've had my Singer 99-13 for a couple of weeks now, but hadn't looked in the top of the bentwood case until today. (I was away for 5 days in that time, if that counts.) I discovered that there is a place to put the knee bar in the top of the case, or at least that's what I think all of that metal is for. The thing is, I can't figure out how it goes in. Is there anyone out there who can post a picture of how it fits in the top, so I can try to put it in there?
Thanks,
Janis
