So glad you found them!
I have "misplaced" the first BOM in a program I am in. I have gone through almost every box, drawer, container, etc., in my sewing room but still no luck.
On the positive side - I have found several things that I thought were lost.
And like you, I have numbered each container, etc., and then made a list of what's in each for a notebook.
Still hoping the lost BOM will turn up in the last 3-4 containers.
