Seems to me it was Scheutzen - made by the same folks make Swiss, I think. I recall the article in Handloader magazine as well, but not much of it. A double 12 bore of some description, of low power, though, compared to the heavier guns.

The Paradox are very well thought of, yet most didn't make more than 900 to 1,000fps, sometimes perhaps as much as 1,100fps. Pretty pokey and ballistics Forsyth scorned due to their arching trajectories and low penetrative power compared to heavy loads with round balls in the same bores.
