In the Double Gun Journal,Volume Seven, Issue 3 from autumn 1996 I was very impressed by "Bengt Berg`s Fantastic Set of Simson Guns" (page 119). There were two guns and no less than nine pairs of barrels in different calibers and combinations, and all barrels fitted both the actions ! Bengt Berg was a well-known Swedish zoologist, ornithologist, photographer, hunter and author of about fourty titles. He made several expeditions where he used these exceptional guns to collect everything from tiny birds up to the really big boys. He ordered the guns in 1930.
The double rifle barrels were: .470 N.E., .360 No.2 and 6,5x57R/.22 Hornet, the combination barrels were .222R/12 bore shotgun (with scope), .470 N.E./12 bore Paradox Explora, 8x60RS/12 bore Paradox besides a set of 12 bore shotgun and another one in 12 bore Paradox ! Interesting to me is the fact that the .470 N.E./12 bore Paradox barrels were stainless steel ( Krupp Nirosta ), which makes me think of the capabilities of today`s gunsmiths. Most will tell You that it is impossible to make a stainless steel double or combination gun.
The actions were perfectly made, beautiful engravings with gold inlays, steel grip caps for spare sights and tangs with fold-up peep-sights.
I think a set like this would be great for an extended hunt, lets say three to six months or a comparable dream hunt!
Personally, would be perfectly happy with a double in .470 or .500 N.E. with a set of 12 gauge shotgun barrels and perhaps another in 9,3x74R/12 gauge and perhaps another in 8x75RS........sorry, I am just dreaming !
