Dear JoeJr,
thank you and all of you so much for taking so much effort!
Your detailed descriptions are fantastic. Thinking about „how to lift the pressure when the foot is up“ had me thinking as well as part number 5 is not attached to number 4 as it is with „newer“ Singers. So I think you are right with your second idea that number 5 has to come before number 4 so it can press against number 4 when the pressure lifting pin is moving forward so tension is disengaged. I didn‘t know there were springs without the eyelet so snipping that off sure helped a lot getting it into the housing. That couldn‘t really be done with the eyelet on.
As you can see the complete assembly looks nearly like a singer with a black numbered dial. Now I think I need to adjust the bobbin tension, as that seems to be not high enough to resist the upper thread on any upper tension.
I attached a video to show you how it is working. Would you agree that that looks about right?

And one final question as you all got me thinking: is this really a 201 or another model?
