Marvelous story, Lloyd!
I wish there were something similar to offer from my own family history. Unfortunately, my father's Leica IIIf had a bit of father-son spite war associated with it so it never resonated with me ... I traded it for more modern equipment shortly after I inherited it and enjoyed my own Leica cameras, those i bought for myself, much more.
My uncle gifted me with his prized Polaroid SX-70 last March, and there's a lovely memory in that—which is, I imagine, part of why I enjoy using it so much.
