Several years ago, I sold one of these puppies, since I never had a bike with one. A modest amount of remorse has set in, and I'd trade a spare NR + modest amount of cash or ?? for a SR good enough for display, that is, worn pivots ok but shouldn't be completely trashed cosmetics. I have the rest of the series, and it seems silly not to complete it. I have several NRs with different patent dates.
