Manufacturer markings are normally stamped on the tip of the long end strap. However there are exceptions where the markings are stamped at the base of the long end or on the short end. Additionally, some straps will have the name and location of the manufacturer as well as the date stamped in different places.
Chinstraps manufactured prewar and the early years of the war bear the full name of the manufacturer, plant location and year of production. Later in the war straps were stamped with a manufacturer’s code (RBNr or RFNr). RBNr is an abbreviation for Reichsbetriebsnummer (National Business Number). RFNr stands for Reichsfabriknummer (National Factory Number). This section will show a variety of manufacturer and code stamps and are presented in alphabetical order beginning with the first letter of each name. For example, G. Schiele, Loburg starts with the letter "G".
