Gary, my first quick look on pic#4 let rise the same thoughts first but a closer look let me doubt. I think it is the unknown owner of the house ore one of his ancestors.
Concerning the wear of the game wardens badge: It for sure is one of the legit variants of wearing it but only the second most variant. Mostly the badge was (and the today´s one is) worn attached to (on) the left breast pocket.
Regards,
