whats interesting about this the 3 feet or Mannlicher Schönauer claw mount is in this case a 4 feet mount with two claws on the rear feet - never see this before
My 1922 proofed M1910 Take Down Model wears a Gerard 'B' scope on claw mounts with two 'feet' in front, two at rear. It was on the cased MS when Grand Dad bought it second hand at Colombo, Ceylon, 1930 or 31.
