I doubt that only 200 were made. They couldn't recoup their production costs by selling just 200 unless they charged a fortune for the lens.
At first the lens was only available with the body. Later, the lens was made available as a separate item. And certainly Rollei made more than 200 lenses for the entire planet.
It's highly doubtful that only 200 were made. Sounds like the typical nonsense from an uninformed eBay seller.
