How to tell which Mac the iPod was synced to?

I recently found an old iPod classic from 2009. The last time it was used was likely around 2013 and it works just fine. I'd used the iPod on a few long flights and "favorited" a large number of songs that I'd like to preserve the ratings for. I assume the best way is to resync the iPod but I can't recall which of my Macs this was synced to.

Is there some way to tell which Mac this iPod was synced with?

Failing that, is there a recommended way to pull some of the metadata for songs I've rated off the iPod?

Thanks
