I tend to agree with KY Jon. Shoot it, enjoy it, and be a good steward. If down the line you choose to sell it, you should have no problems based on how Model 21's move and sell. Younger folks are taking an interest in some vintage guns. The problem that I see however, is they expect them to be flawless.

As a museum curator, I see a lot of valuable items that get donated to the museum. Most family members do not want to sell them. They get them appraised by an outside source, donate the artifact(s) and take the tax write-off.
