Way I see it, you can advertise it in local shotgun competition shooting crowd in it's current condition and see if you get a hit. Barrels a little long for skeet and some of the other sports, but would work well in trap and most of the competition shooters hunt. Sounds like a nice goose gun for a lady shooter. That's the crowd I would get the word out too.

If it doesn't sell, then I would think try the factory replacement stock would be more desireable to a potential buyer than the adjustable stock. I know, I know... shooting difference is minimal, but the shotgun crowd can be uber-fickle about how their gun looks.
