Salesmen would travel to regiments with a catalog proposing makers models ... either with a plain blade or etched with a few patterns to choose from ... these patterns were the basic models with no customization at extra costs obvioulsy .. Then you could also order a special customized etching for a company or a special event ( birthday, presentation, etc ) at even more expensive ... I read that you could also choose the color of the lionhead's eyes with a few companies so that can add extra confusion about that Customs / Heer matter
