Günter, I lose the concern in the mid 1930s. Don't forget his loyal companion. It is difficult to search with other Otto Bocks in Berlin(established in 1873):
As far as I can tell this is not our beloved Otto Bock and if not some of his info may be entangled in the info thus far.
Info suggest Otto Bock, Senior, was a whale of a taxidermist and he must have had multiple Royal appointments:
"Otto Bock Königlich Hoflieferant Tierausstopferei und Jagdgeräte Handlung Berlin W 8 Kronenstrasse 7
Kollektion ausgestopfter Fischfeinde "
"Hoheit der Großherzog haben dem Otto Bock, Inhaber einer Waffenhandlung und Tierausstovferei in Berlin, das Prädikat als „Hoflieferant" zu verleihen geruht. Neustrelitz, den 23. April 1906."
This is an April 1906 dubbing but he advertised as being a supplier from circa 1900/1901 onwards.
Kind Regards,
Raimey
