At this time very little is known about this Gun Maker. The first reference to him is from an 1880 Heidelberg Directory seen below.
A second Directory listing is from 1887, seen below.
The Pape & Kellner Archive cites a 1900 reference which has not yet been found. Heidelberg Directories for 1872 and 1874 have been examined with no listing for him. We have an article about a hammer Drilling and images of a hammer shotgun showing his talent.
