Having formed Conway Stewart as a Limited Company in the UK the trademark was registered in Europe and Asia to ensure worldwide security for the brand. Having researched Conway Stewarts previous manufacturing history and techniques Don Yendle wanted to keep true to its core values from 1905. What followed were 3 years of research into Casein and plastics including vulcanite for barrels and feeders for nibs. The company even used a Birmingham-based company who still used a 1-metre pantograph to make the miniature moulds for the pen clips in order to keep the detail in the clips. All of the new clips were exactly the same size as the originals so pen collectors would have spares for the vintage pens they wished to repair.
