Textbook strap for the bakelite 6X30 Dienstglas made by cxn

Textbook binocular or Dienstglas strap in good used condition. This is the specific example as issued with the bakelite binoculars made by cxn (Emil Busch, Rathenow), easily recognizable by the two extra holes! The leather is rather supple but has a tear at one of the extra holes!
