Singer Sewing Machine 1939

I am curious about information on this model, how much it could possibly be worth, etc.

I have looked up the serial number and found it to be from 1939, I don't believe the table is the original as it has more of a retro look to it, but any information that anyone can provide would be amazing. Thank you in advance!

We did plug it in, it works, and the light on it works still as well.
