Hi Len,
I am sending your question to HISTARCH, an on line nation wide group of historic archaeologists who weigh in with support, guidance, opinions, and advice. (I'll forward any replies to you and also David Hoexter, if that is ok.)
Also, yesterday I contacted the Strong National Museum of Play - the newer iteration of where Petra Williams said she was sending their items. The librarian told me yes he found records of numerous donations, but that since the change to the play element, the objects were probably no longer in their collections. He was going to check further.
