The case "Oxford" is a real Montblanc product from the 1970s to 1980s, qualitatively however clearly settled below the later Siena cases. It was intended as a cheaper variant, among others, for the Slimline and Noblesse models. The designation can be found on an enclosed cardboard strip together with the model number 2450 and the article number 12067. On the official website, this older range is no longer documented.
