I am in the same situation in that my only child divorced and then passed away. The Grand kids do not show much of any interest and my wonderful wife puts up with my hobby but also does not want to have to deal with it when I am gone, even though I am expecting it to be a lot of years in the future. I have talked to a local gun shop that will take collections on consignment and will give 80% of the sale price back to her. They will even come and pick them up but (there is always a but) what about the firearms that have special meaning.I have thought about giving those with special meaning to the NRA but it is not like they are nib firearms but ones that I received from my Dad and Uncle that were used by them and passed on to me. Those are the ones that will be hard to go to someone who didn't know them.
