Years ago I did work for an older widow in our town.
When her husband died her son got the guns, but missed one. He later died, too.
She knew I liked guns, so she told me to take an "old shotgun" that had belonged to her husband and have fun with it.
Since her son and husband were dead she didn't figure it had any value except to someone like me who liked guns.
The only problem with that theory is that it was a Winchester Model 21 in a custom case with beautiful wood.
Probably worth thousands back in the 1980s, and she had no clue until I told her what it was worth, and I put her in touch with a Winchester collector I knew who gave her a good price.
