–Comment: I think David Knell as Sam Clemens (aka Mark Twain) in bibs with one strap down. Putting on bibs. But very brief scene and partially and from a distance shown.

Another repost.
I don't remember all texts.
I don't know other episodes, but obiously very few other bibs scenes if any.
Most episodes are older historical plots. Series still running.
