Hartmann & Weiss

Hartmann & Weiss GmbH is a Hamburg-based custom sporting firearms maker founded in 1965 by two ex-James Purdey workers. They make sporting arms, including shotguns, over and under, falling block single rifles, and bolt action rifles based on Mauser-98 and several other modern actions. They have produced small numbers of double rifles, in calibers from .375H&H to the .600 Nitro Express.

History
Otto Weiss was a gunsmith who worked at Merkel in East Germany before fleeing that country in 1958 for England, where he initially worked at Purdey's. Five years later he relocated to Hamburg to work with Gerhard Hartmann as a custom gunsmith. In 1964 he and Hartmann founded the company. Three years later, an associate named Peter Nelson established a second location in England.
