"Where do DeFourneys rank in Belgian Guns ?"
They, like most all makers, supplied a range of original quality grade guns. Quality grade for quality grade and current condition for current condition, I believe you will find that their guns fall in Brand Value level four; 1/4 the fair market price of a BV1 (Boss, H&H, Purdey, or Woodward) gun. There are a few Belgian makers that have achieved BV3; 1/2 the market price of comparable BV1 guns.
Note/remember, the maker's name does not define the original quality grade of the gun.
