On the Singer 185j, where is the serial number? I have tried locating it on mine and I just can't seem to located it. I have quite a sewing machine collection too. I love sewing machines. I started out with a singer treadle that was my mother in-law's godmother's. It need some refinishing to the cabinet. It all went down hill (according to my husband) from there. I have portables and machines in cabinets. I display them all over the house. Well, some of them anyway, others are in a shed waiting to be refinished and the machines cleaned and oiled.
