[[Osmia]] had a great initial success, becoming in a short time the second largest producer of pens in the country, so that a plant was specially created to produce pens. In the late '20s however sales had slowed and margins were weak, so the company went into financial troubles. In this period [[Parker]], who was trying to expand its business into Europe, began to take an interest in [[Osmia]] which was acquired (or with whom took an interest, sources are unclear) in [[1928]]. In this period the company produced the [[Duofold]] for the European market, characterized by the imprint ''Parker - Osmia A. G. Heidelberg''.
