I have an old portable Singer machine that is in a brown & beige case with latches on the side. The handle is marked Singer. The machine is all black no decorative markings and the number that is on a little plate at the front left side reads AM057452. There are some other numbers on the back that read
CAT BZ 15-8
SS AU 52-30-24
Mfg. Elizabethport, NJ
Does anyone know what I have or direct me to a site to find out. I went to one site but the number I have wasn't there..thanks for any help.
