I have a 99 which belonged to my mother in the 40's. I learned to sew on it and when my mother died I brought it to my home. My older daughter loved to sew and she used it often. It's been in storage since 1983. I had a new house built last year and when I moved into it, I brought the 99 with me. It is in a very nice sewing cabinet. I have not tried to sew with the machine because I've been so busy with other things since the move. I can remember that it was a nice, solid machine and never had problems with it. I think I read somewhere that the 99 was a 3/4 size model and it is very heavy.
