My greatest find was the trains I ran as a kid. One day back in 1989 I went to visit my great uncle. In his kitchen were several boxes I recognized. They were the boxes we stored the 2 train sets I grew up with. When I inquired what he was doing with them, "I am throwing them out" he replied. As I recall, trash day was the next morning. I told him I would take them and he objected, "they are junk" he said.
Thirty + years later... Christmas morning, 2022.
The 671rr and its original consist as my dad ran it back on Christmas morning 1952 when he got it.
