Same as in 1840 Carl Gottlieb Hnel(hold "alt" then press "132" on the number pad & release) hung out his gunmaking shingle with the C.G. Hnel name. I would guess it was made post 1912 - 1919. I don't think the serial number to be in that of Hnel's target arms. The preponderance of evidence tilts the scale toward Robert Schlegelmilch for the RS and of course there are a few other possibilities. But he would have knitted the tubes together. The RS mechanic was sourced by Lindner and has effort that parallels Jean Falla, William Ford, Gebhard Helmuthhauser, Louis & Wilhelm Kebler, etc. I would not doubt that the *H and the Gothic H on the tubes to belong to Gebhard Helmuthhauser. The *H & RS stamps cease by late 1920s as I think Robert Schlegelmilch closed his shop in 1924.
