I have two cameras sitting around on the shelf. They are: Zeiss Ikon Ikoflex Favorit (887/16) with 75mm (1957-1960) and a Arco 35 Automat D (f2.4 lens). I purchased both of them for a total of $31 and the bodies appear in very good condition especially the Zeiss which is in excellent condition and came with the original case. I am unfamiliar with both of these models. Any thoughts on having a CLA performed on either one of them?
