This Hensoldt "Solar" with prism optics is very early. If I believe old catalogs, f.i. the AKAH one, it was already out of print by 1908, replaced by "new" Solars with lens optics. From the position of the "claws" I believe it was once fitted to a sporter on a M88 action or a Haenel 1900. At the time this scope was made the .22lr was not fully developed and mounting expensive scopes on .22 bolt action "garden" rifles would have been an outright silly idea. Such low-magnification scopes, still in a somewhat experimental stage of development, were mounted by well to do guncranks on full-bore, big game rifles then. Remember, scopes of about 2.5x magnification like the Lyman Alskan, Weaver K2.5 or Noske were regarded the last word for big game hunting 40 years later in the USA by men like Keith, O Connor or Whelen.
