Not sure about the end. Some of them do have weird stuff.
More pics please. Can you open the pics in paint and do some coloured circles or something. Showing from where to where and the like.
I will have a look what i have here. I pulled a Viking apart yesterday. It wasnt a 444H But i might have something here that will work.
Most bearing/engineering supply places have a range of springs. You could guess the length and strength, you could test it weight for distance with an old style fish scale but keep in mind with those three pulled loops it will change things.
