Perhaps a video showing how the needles and bobbins thread and feed. I know a 201-2 threads differently than a 66, but it would be nice to see.
I agree with the contrasting thread too. That makes it show up.
And one last thing, keep the videos short under or around 3 minutes for those of us with dial up.
And now a question: What would a 206 run dollar wise? I've wanted one of those because I've read they were Singers first ZZ machine. Don't know if that's true or not, but they do look like the classic black cast iron Singer and they are a ZZ. If you don't want to post a dollar figure you can PM me.
