The Superposed Grade I Lightning configuration brings together Browning’s classic over/under design with useful field features. This example is chambered for 2 3/4 inch shells and uses 28 inch Special Steel barrels with fixed chokes. A solid matted rib and a small brass front bead provide a clean sighting plane.
Controls are straightforward and proven: a single trigger with a barrel selector, plus a tang-mounted safety. The receiver is marked "Lightning Browning" on the top tang, and the gun carries a 2-round capacity with break-action operation.
Stock and forend appointments are true to the Lightning style. The walnut stock has a high-gloss finish and a round-knob pistol grip, paired with a ventilated recoil pad and white line spacer. Up front, a checkered slim field/splinter-style forend with Browning latch assembly offers a secure grip. There is a very slight right-hand cast off for natural handling.
Origin and markings are well documented. The gun bears Belgian Liege proofmarks and the barrel rollmarks include "Special Steel" along with U.S. patent numbers 2205379 and 2353851. Additional markings read "BROWNING ARMS COMPANY ST LOUIS Mo. & MONTREAL P.Q., MADE IN BELGIUM," underscoring its Belgian manufacture in 1970.
Versatility is enhanced by the included sub-gauge tube set. Full-length insert tubes for 28 gauge and .410, plus a 20-gauge full-length insert tube, are accompanied by corresponding ejector components and the required tools, all housed in a fitted hard case for organized transport and storage.
