As usual Axel E. has already answered a very similar question in GGCA publication #47/Winter 2011 on a copy retailed by Fritz Schumacher of Aachen. The design is one under 1910 DRP 229533(applied in 1907).
Quite a bit of machining, so I wonder if Friedrich Stendebach sourced and if so who would have performed all the effort for the complex beast. F. Stendebach listed as having shingles in Augsburg, Frankfurt am Main, Leipzig, Säckingen & Suhl.
Friedrich Stendebach & Burkard Behr had crossed swords by this time.
