You might want to clean it yourself. Often all these old machines need to work again is a good cleaning and oiling. Cleaning it yourself will make you familiar with the machine and how it works. You will also gain the confidence and experience to maintain it yourself instead of bringing it to a sewing machine shop for maintenance.
Even if you don't want to do the work yourself it would be a good idea to read the stickies and watch the videos on how to clean and care for old sewing machines. It's easy to damage the decals if you use the wrong cleaning products.
