The Scott 410 would not have a lot of value here. However, almost any sxs 410 in decent condition commands a respectable price.

If the Brownings are Belgian made, they will bring a bit more with the collectors.

The Greener will depend on condition. If it is in decent shape, a lot of people would pick it up as a project gun for conversion.

If you can get hold of Greener Martini actions, they would be worthwhile.
