Dallmeyer Telephoto Attachment

Date: July 29, 1896
Notes: This is the matching teleaccessory for the Stigmatic Series II No. 5 below.  Serial No. 55,981 and the same lens that is photographed in the Lens Collector’s Vade Mecum.  This thing is incredibly hard to focus and responds closer to f/32 when the No. 5 is full open.
