Welcome Missykay!
That one is a beauty! I love the colors. Check the chrome knob on the handwheel. Make sure it's turned all the way away from you. It could be as simple as the machine is in bobbin winding mode. If it's in the right position and still doesn't turn, chances are the machine is stuck from sitting so long. It's nothing a little sewing machine oil and patience won't fix. Check the stickies on cleaning and maintaining these old machines. Make sure to stay away from harsh cleaners. Some will harm the finish.
