next was a visit to the old bike shop i use to frequent when i lived at home with my parents. it's been there as long as i can remember. rummaged around and found me some of these NOS... not sure if i have a use or need for them, but snapped them up anyway. worst comes to worse, i'll share with the community.
they are all "flat rings" so there's no chain pick up it looks, guessing for SS purposes???
