What happened to Pernell Roberts wardrobe from Bonanza?

Pernell Roberts' wardrobe from "Bonanza," where he played Adam Cartwright, was reportedly stored after the show ended. In 1973, a significant portion of the show's costumes, including Roberts' outfits, was donated to the Western Costume Company for preservation. Over the years, some items have appeared in auctions and exhibitions, but many remain part of private collections or museum displays related to Classic Television history.
