I have a mod 28-2 and mod 60 no dash that were left to me by my grandfather. I believe the 28-2 is unfired and the 60 has been fired very little. Both have box, paperwork and tools, and the mod 60 has the receipt from 1976. Is there any reason to keep them as is or should I take them out and shoot the hell out of them. I have no plans to sell them as I want to pass them on to my son some day.
