I rescued a vintage sewing machine a few months ago. It is blue and does not have a manufactures name on it. It says "stretch stitch" on the front. The manual had to be thrown away, it was wet and moldy. It has a metal tag on the bottom that says "twi" model 901. I took it in to my local sewing machine repair shop and was told it was manufactured by a company called "happy". I would love to find the manual for it. It is my understanding that Happy manufactured for Montgomery Wards.
