Gebruder Weyersberg King's Head marking on Civil War Horstmann & Sons' sword
Weyersberg was essentially a family sword-making dynasty. This family is recorded as making swords as early as the 1400's, and was located near Solingen, Germany. They produced blades with the King's Head and a rooster marking. Prior to the Civil War, we find its blades used by such makers as Frederick Widmann and Horstmann & Sons. During the American Civil War, Horstmann & Sons used many of Gebruder Weyersberg's blades on its higher grade swords.
