Welcome. I think it is rather ambitious to get a sewing machine to sew upholstery. Have you sewn before?
bkay is correct about the knee lever being the controller and some being able to be used as a foot controller. Some just have a short cord and would need to be rewired to be able to use as a foot controller.
Did you get a manual and attachments with your machine? I'm guessing that it probably is a direct drive, which means that the hand wheel goes the opposite direction from most domestic machines. The serial number should be either in front or behind the pillar (the upright part of the machine that has the hand wheel on it). There are a couple of sources for info about vintage White machines at but will have to scroll down the pages to see the electric ones

We like pictures. In order to post pictures on Quilting Board, you will probably need to reduce or compress the picture to a
file size that is smaller than 2MB. How to post images can be found at

Don't forget to scroll over to the far right to find and click on the "

I have found that only the big red "Reply" button or "Quote" work to give me the paper clip icon to work for adding pictures.
