Hi again Ayrzee 
Had a very long look at all of what I have and it breaks down thus :
Suntour Winner 7 speed screw on block, first 2 larger sprockets are 4 pronged type and I have 28t, 24t, 23t, 21t in this form. The smaller sprockets are no use to you I'm afraid as they "are screw-on type". Sorry for the confusion buddy, but it's only when you take these things apart that it becomes noticeable they are screw-on.
Hope you find what you're looking for All the best yours Laz.
