Hi Ace,
I have combing through many YouTube videos but cannot find it yet. I came across it while looking at toy train layouts and the piece was professionally done by a local t.v. station, if I remember correctly. It focused on the story of the older gentleman giving or bequeathing his layout to a kind younger man who befriended the older man. The attic was rather dusty and unfinished, perhaps an old farm house. That is about the best I can remember. I did a screen captured to get the basic layout in a photo. Then I enhanced the shot in an editing program to brighten and sharpen it to reveal more detail. I will continue to look for it. I believe I chose the suggested link from a photo of an old tinplate steam loco, like a little 0-4-0 toy steam loco.
Take care, Joe.
