Enjoy your 'new' toy. It is the neatest machine to sew with. I have my mother's and was lucky to find the card table for it. It always has a perfect stitch. I retired two years ago and became interested in the old ones. I picked up a white/green one recently. For some reason, the 'feel' of the white one is not the same as the black. Would like your opinions of the white compared to the black. I, also have a 15-91 in a cabinet that is wonderful. It has a perfect straight stitch and can sew anything. (It, also, could be used for an anchor). There's a couple of Yahoo sites for the old Singers that were very helpful when I took apart the 15-91.
