I have recently located my grandmother's Singer sewing machine with a cousin in another state. We both learned to sew on this machine as young girls. I would like to locate and purchase a machine like it. She hasn't sent me pictures but has given me the Serial # AH168407 and the motor is a BZ9. It is in a bentwood case and is the matte black crinkle finish (I think it is referred to as "Godzilla"). According to the serial number it is a 128 made in 1947 in Elizabeth, NJ and has a vibrating shuttle. I found some info in an Adjuster's Manual on the singer website that said the 128-23 has the BZ9 motor. Is there any reason I should think it is not a 128-23? I would love to find one in good condition. Any recommendations?
