there's more than that too. Even my memory serves, Ken Hanke's book, Charlie Chan At the Movies, tells that Sidney Toler has a cameo in the movie, Duck Soup. In the music number about going to war, he's supposed to be one of the general who stands up with a quick salute. You'd have to tape it and freeze frame each guy. If this is all true, he'd have a mustache/goatee combo.
