Even though FN’s Superposed was mass-produced, the labor-intensive gun was comprised of more than 70 individual parts and required 155 hand-fitted assemblies, plus the artistry of engravers and woodcarvers. The Superposed was launched in 1928 with a price of $107.50. The guns initially had double triggers, but in 1933 Val invented a Twin Single Trigger that alternately fired the barrels by either the front or back trigger. This was replaced by a single trigger with a tang-mounted barrel selector in 1939. The gun was first offered in 12 gauge, and 20 and 28 gauges were soon added. Later a .410-bore model was introduced. There was no 16 gauge. Each chambering had its own serial number range.
The Superposed was a spectacular shotgun made in escalating levels with Grades I through VI, primarily reflecting external embellishments. In the 1960s classifications were changed to Grade 1 and post-war epithets of Pigeon, Pointer, Diana and Midas. S.P. Fjestad’s “Blue Book of Gun Values” lists more than 50 variations. Since 2001 the Superposed has been designated as B-125 and B-25 bespoke guns from the FN Browning Custom Shop in Liège.
The 12-ga. Superposed Grade I shown here was made in 1952 and purchased by the current owner in 1991 for $800. It is in NRA Excellent condition, retaining its original horn buttplate, crisp hand checkering and engraving. As such, Fjestad’s “Blue Book” values it at $1,825 —a virtual bargain compared to the cost of ordering such a gun today.
