Hello, out of THE book concerning german knife and sword makers, first

the mark L.H.BERGER (with additional "Behn & Co"): Purveyor to the court, Kiel. The mark was recorded on naval officer´s dirk dating from 1900-1910. Nothing has been discovered about the business exept a presumed connection to the Berln firm listed next.
The mark L.H.Berger, Collani & Co: Berlin SW68, Friedrichstraße 210 in 1939. It is assumed that L.H.Berger had taken over another independent supplier of uniforms and equipment in the 1890s, but incorporated the name in the newly constituted business.
The name has been recorded on a privately purchased Füs. saber 1860 and several officer´s swords.

Unfortunately nothing more on this firm and I personally have the feeling that the Damast sword smith was somebody else who worked for this firm.
Regards,
