I recently bought a vintage hallmark sewing machine. It is lavender in color and it zigzags and has built in buttonhole stitch and it takes cams. It is made in Japan its model number is 763BH. But I have been unable to fine out anything about it. I figure it is a clone from the Singer machine. But that is only a guess. Does anyone else own a Hallmark sewing machine? Or know how I can find any information about it? I have spent hours on the web and found nothing about this sewing machine. It must not have been very popular in its life time.
