The January 16, 2024 edition of the CBC radio show "As It Happens" has an interview with Gerry Vogrincic, the doctor who bought the book in 2007 and just sold it.
There's a transcript of the interview here [1]. Search for "Old Anatomy Book".
The audio for the entire episode is here [2]. I don't recall how far into it this interview occurs. (I've sometimes found their interviews split into separate clips, but if that's the case here I don't know where to find it.)
