Our Assessment: After the death of John Browning, his son Val would complete an over under shotgun with a single selective trigger and ejectors; the Superposed was introduced in 1931, it was an instant success; the factory did not produce any of these shotguns during WWII but just after the war ended, the factory came roaring back to life, creating some of their best product to date. This is a post-war FN produced 20 Gauge Lightning from 1967, in about Fine-Plus condition, retaining about 97% of its metal finish. The action is spot on and the trigger is crisp. Val’s SST is still known as one of the most reliable and ingenious of its kind, even though the patent is nearing 100 years in practice. With barrels choked Full over Improved Modified, this is going to make for a nice shotgun for the skeet fields. Please see our photos and good luck!
