Type of Finish: Blue & Bright

Finish Originality: Original to Engraving

Bore Condition: The bores are mostly bright. There are some spots of light erosion. In my opinion, these bores rate 9 out of 10.

Overall Condition: This shotgun retains about 95% of its metal finish. There are some scattered spots of light oxidation and discoloration on the frame. There are a few little scuffs on the barrel set that have lightly thinned the finish. There are a couple of hairline scratches. The trigger has been modified and a portion of the spring can be seen through the trigger. There are some scattered light handling marks. The markings are clear. The screw heads are sharp to lightly worn with strong slots. Overall, this shotgun is in about Fine condition.

Mechanics: The action functions correctly including the ejectors. The safety does NOT set automatically when the action is opened but functions properly when manually set. We have not fired this shotgun. As with all used firearms, a thorough cleaning may be necessary to meet your maintenance standards.

Box, Paperwork & Accessories: None.

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 12 Gauge from 1973, in about Fine condition, retaining about 95% of its metal finish. There is some wear to the metal and wood but the action is still 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 Fixed Full over Fixed Modified, this is going to make for a nice shotgun for the field or the range. Please see our photos and good luck!
