I've been working on my newly acquired blue Morse 200 clone.

It's a pretty machine and runs oooh sooo quiet, but it had a few issues with the tensions.
>1st: No bobbin case.
I had a couple of spares so I picked the best and put it in.
>2nd: The presser foot lever would not release the top tension disks. Nothing I could do would make it release. There is nothing out of the ordinary with any of the parts. No burrs, I cleaned all the pieces thoroughly. Nothing appears to be bent. What I did find was an extra locating washer between the tension disks and the +/- ring. I took that out.
Also found a tiny bit of rust in the pocket the thread take up spring adjusting collar fits into. Cleaned that out.
Turns out the release pin was too short. I had to custom make a longer one so the top tension would release.
>3rd: The top tension was way too tight. I had that thing apart many many times and nothing would help. Removing the adjusting knob and spring and sewing basically without a top tension was much better. But that ain't right.
There is something "not right" with that top tension and face plate though. I can put one from one of my other clones on it and the tension works good. I just can't figure it out.
>4th: The top thread would fray and break when the machine was run fast and the tension was at or close to normal. That was caused by a chewed up hook. Check out the pic below:

You can clearly see the pits and pock marks in the hook. The only thing that could have caused this is an incorrect needle. In this case a 20x1.

Sorry about the blurry picture.
This is a 20x1 needle put in and slowly rotated until the needle and hook damage lined up. It's a perfect match.

The correct 15x1 needle didn't come anywhere near the damaged area.
The damage was so severe it was causing the thread to fray and break.
It took me 45 minutes to stone and polish the burrs off the hook surface. The gouges were so deep I could not remove them all.
Once the hook assembly was cleaned up and put back in I worked on the top tension again. No luck until I took the second washer out of the assembly.
Now I've got it so it will sew decently.
I'll do more tuning after I get it all cleaned up and re-oiled.
This thing better sew a nice as it looks when I get done with it. If it don't .... I'm gonna
