I just watched it (you can get it on your computer from the PBS website after the show has been broadcast). I would love to have read those diaries! Unfortunately, nobody mentioned until the very last scene that it's a good idea to share this material with nearby universities or museums so that others can access it.
This was a collage of scenes from the last 1 or so years, all related to CW-related items. The 2017 value was given for each item in addition to the one given when the episodes ran. In some cases the value changed quite a bit, some up, some down.
I recently read about the "Boy Colonel" Henry Burgwyn at Gettysburg, so it was great to see those watches.
It's definitely worth an hour of your time if you can catch a rerun or stream it on your computer.
