I have been searching for a 1952 336 32 Win for over 40 years.
When I was a teenager my sister and I got in a car accident. My dad sold his prized Marlin to help pay the medical expenses. After he died I was going through his papers and found the receipt for it with the serial number. Been checking the numbers on every 32 special 336 ever sense. If I don't find it my oldest son will continue the search.
That right there sounds like a worthy quest. Have you thought about posting the story and a request for help over on the campfire?
