Rolleicord I Model 1 (factory Model K3 - 510) was known colloquially as the 'Tapeten-Rolleicord' (wallpaper Rolleicord) in Germany.
The camera is nickel plated and decorated with a trompe-l'oeil grid on all sides bar the bottom. A depth of field table has been attached to the back. The camera was sold with depth-of-field tables in German, French (this unit) and English. In parallel with the decorated versions, a plain model was also produced, covered with standard black leatherette. Towards the end of the production run, a removable camera back was introduced,, whch then allowed for optional back replacements, such as a 35mm adapter (Rolleikin I) and a sheet film adapter.
