Heinrich Scherping (1831-1913) circa 1862 became Hofbuechsenmacher (court gunsmith) to the royal court of Hannover -- which went into exile in Austria after 1866.

Scherping was primarily a retailer of private label sporting arms. Many are posted online, some identified as to manufacturer.

In 1897 the Scherping business in Hannover was owned by the brothers Heinrich (d. 1929) and Johann (d. 1928) Eckebrecht.
The company "H. Scherping, Hofbuechsenmacher, Hannover, Inh. (owner) Eckebrecht" still advertised in a 1937 Wild & Hund hunting journal.

Based on the ultra-modern styling of blade and mounts, the knife is no older than late 1920s, and is probably more recent.

I could find no connection between Heinrich Scherping of Hannover, and Hermann Goering's Landesjagermeister Ulrich Scherping (1889-1958), who was born in Krakow, Pomerania.
