Your words are shaped in the form of story; Sons are selling the antique vehicles n things of their father. I am also thinking about the time when those things were purchased( that would be the time when things used to simple) and these things were brand new but now time has aged these things and owner has closed his eyes forever.
Now his things, some of them would be his favorite and may be he might thought not to sell them, are going from that area.
These are still worthy and those people who consider them antique know the real worth of them.
It's good to know there's people who want to preserve history and it's surprising what they'll buy. There's a lot there, so many years of things that people valued once, and will again.
