Raimey,
I have a pin-fire rifle marked E.H. TANNER IN LIEGNITZ. Its hammer is similar to the one on the C.D. Tanner pistol above.
With kind regards,
Jani
Seems that when the gunmaking business in Herzberg dried up and apparently to renew the royal warrant one had to have an address in German that the Tanner boys went their separate ways with Hermann to St. Petersburg and E.H. & Otto going to the Breslau/Liegnitz/Groß-Glogau area. Piotr J. Bochynski & I were exchanging info he sent me this advert.

E. H. Tanner - Groß-Glogau / Hlohov 1892 Advert
In 1880 E.H. Tanner filed DRP 13098 for a rear diopter.
