I found your abandoned draft version of a translation of the German "Rollei" article in your sandbox and incorporated it into this article. Since your translation is based on the German article as of 2011-09, it still needs to be re-synchronized with the current version of the German article in order to take advantage of any improvements/corrections/expansions in the German article since then. Also, some of the info in the 2011-09 version is obviously outdated and needs to be updated and merged with the info from the English article. Some of the newly created redundancy needs to be removed. However, this is work in progress and will naturally happen over time. Thanks for your translation.
