I have an electric singer in table. The number I found on the machine is EL 925099. I don't know much about it. I've had it for a long time. It stopped working and can't find anyone around here to work on it, everyone tells me it is to old and I would have to take it to an antique shop. The shops here say they can't help. I know it is and old machine but how old and what is it worth?
