Very important point that Fred brings up. I once was given two firearms that had been through a fire serious enough to severely charr the stocks. One was a Winchester Model 92, the other an obscure B'ham built 12 gauge double. All the springs in both guns were completely useless because of the heat sustained in the fire. That was enough to cause me to pass on completing restorations on both guns. I felt that if the heat was enough to ruin the springs and severely charr the stocks, no telling what else might be ruined as well.
