Hi, I've just purchased a 1960's bubblecut Barbie doll that is marked 1557 across the inside top of her right leg . The number runs straight across. I
have 5 other Barbie's but although some have numbers on their legs, none has a number like this. Could it be that someone has exchanged her original legs,
or did Mattel mark some early dolls this way? Many thanks for any answers
