I just couldn't pass on when I saw her. I don't know anything about vintage machines but learned on a Singer treadle when I was very young.
Can anybody help me identifying the Model and Year?
It is missing the side plate and foot. No idea if it works but I don't dare to plug it in as is. I feel like learning how to take care of it. Would love to see if works.

thanks ahead for your help.
