As a side note, my cousin in Canada recently emailed her response to a query I made two years ago. It seems the family's 616 Kodak Box Brownie my stepdad bought in 1943, is now in the hands of my sister-in-law, my stepbrother's widow. She has no use for it but refuses to part with it. This gal made it her life's goal to get our family's entire estate, but my stepmom lived to 102 and when she passed in 2021 there was nothing left.
I did get almost all of the family's original 616 negatives when I was in Canada in 1982, so in that way I'm the one best off.
