I too fancy Heinrich Scherpings fine firearms, I have A top lever hammerless drilling
16x16x9.3x72R made approx 1918, I have a georgeous 98 mauser in 8x60S made 1926, & a 22 cal.
target pistol falling block, set triggers. So I will pass along what little I have read.
He was listed in NUER STOECKEL a gunmakers directory that ends in 1900: "Heinrich Scherping"
located in Guestrow Mecklemburg and in Hanover,Germany. Mentioned between 1831 and 1913.
He is listed as a ginmaker to the court in Guestrow, and in 1913 in Hanover. He became a member
of the blacksmith Guild in 1862 and two former addresses are given. I have seen his guns from as early as 1880s to late 1920s and all have been fine work. Hope this helps and if anybody
comes up with any info on him or any of his guns please share
