Not lost or stolen, but sold before I enlisted... Verona SX 405 Combo. I was absolute lights out with that shotgun and I sold it before I headed off to basic thinking I would never come back from basic and Iraq. I regret selling that shotgun every day of my life. I only had it for two years, but it had already taken two deer with the rifled slug barrel, a turkey, about 15 ruffed grouse, 100's of gray squirrels and rabbits, crows, and more greater canadas than you can shake a Maxus at. Loved that shotgun, never jammed up no matter how cold it was and I can't find another one anywhere. When I was a lodge manager at Dick's in NY (back when it was a family owned business), I bought it for $249.99 with both barrels and an aluminum hard case. Employee special pricing. Came with 5 chokes, too.
NEVER SELL YOUR GUNS. That's the lesson I learned.
