I have written a fairly lengthy technical piece to summarize & save the research about the ZI that I have posted from time to time. Mike Elek has graciously agreed to post this on his blog website so that it can have a home. I have called the article "Inside the Zeiss Ikon" & it can be accessed under "Other Comments" on the home page or in "Other Views" on the ZI Blog page. I expect that Mike would welcome contributions from others. The url is http://elekm.net/zeiss_ikon
Thanks to Mazurka for encouraging me to do this.
