Yes Miriam, that is a bobbin winder in the top. Yes, I've sewed with it and it wasn't a problem to thread. Just wanted a manual to find out about the knob that's around the reverse button. I was trying to find where the stitch length is. It's not the push button and turn knob next to it. So it has to be that knob, but it's stuck. Or someone tightened it too much, OR it might just be stationary. Who know? This machine is called a Universal De Lux.

Claudia, did you sew with it the way it is threaded in the photo? If so, it probably sewed but you don't have the thread going under that bar next to the tension disk like it should. The thread goes from the tension check spring -then under that bar on the left side of the tension - up to the take up lever thread guide.
