Really the Rolleicord from the model I to the model Ia has a Heidoscop- Anastigsmat 4/75, from the Ia third version and "Polizei" has a Heidoscop- Anastigmat 3.2/75. From the Rolleicord III -at least in part- the viewing lens was called Heidosmat, Prochnow has an error in the Rollei Report II because he calls Heidoscop -Anastigsmat the viewing lens for all Rolleicord models including the Vb, I asked him about it and I couldn`t obtain a clear answer, perhaps the name was not changed in the Rollei original document or perhaps was a typo because he took photographs for the book where you can read the name Heidosmat in the Rolleicord viewing lens clearly, f.e. the Rolleicord IV in the page 22-440 has engraved "Heidosmat" in the viewing lens and then the camera photograph is right and the name in the model description is wrong, anyway all post-war Rolleicords and some pre-war Rolleicords have a 3.2/75 viewing lens.- All the best Carlos __________________________________________________ Correo Yahoo!
