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.
