Lasse, As you may already know Goerz was one of the companies which merged to found Zeiss-Ikon in 1926. Various makers cameras continued to be sold but under the Zeiss-Ikon name. You might want to try posting to the Zeiss Ikon Collectors group on yahoo - http://groups.yahoo.com/group/ZICG/
I posted a question there about the 1927 Zeiss Cocarette I picked up and received helpful answers. That camera had an unusual way of loading the film and I was misloading it. The camera produces 6x9cm negatives (on 120) but I was getting 4x9cm negatives - until I learnt my mistake. Pacific Rim Cameras have an excellent referenc to the various Zeiss models which may help you identify exactly what you've got. http://www.pacificrimcamera.com/pp/zeiss/zeiss.htm Good luck. ---------------------------------------------------------------------- Fred Widall, Email: mailto:[EMAIL PROTECTED] URL: http://www.ist.uwaterloo.ca/~fwwidall ----------------------------------------------------------------------
