I have a Rolleicord and dont the the model or date. I searched the web and the closest match i could find was a limited police edition of 500 but im sure this is not that one, i wish i could be that lucky! The seial number 742xxx, viewing lens is Heidoscop - Anastigmat f=7.5cm, Taking lens Carl Zeiss Jena Nr2662976. The camera is in rough shape with only one shutterspeed.
When i checked the web it seemed every taking lens was a Heidosmat but mine is a Heidoscop
