Opera glasses with adjustable focus, slightly discoloured.  With old leather case. Age unknown.

In a leather case marked "S. Friedeberg Söhne. Königl. Hofjuweliere. BERLIN" [i.e. S. Friedeberg & Sons].  The case itself is rare.

Please note: it is unknown whether these are the original glasses for the case, as there are no maker's marks on the glasses, but they have been together with the case since the 1980s (when purchased by the original owner).
