Glad to see I'm not the only one who notices little things like hats. Several of the hats were passed around to various cast members. When Tom was introduced, he was wearing a multi-fabric/design brownish cap that a different cast member wore in "There are Gypsies at the Bottom of Our Garden." That actor was the man Foggy approached and wanted to continue telling him about his war stories. The guy quickly ran off down some steps.
Howard is sold a hat/coat rack by auntie Wainright, and she threw in a ladies white staw hat to clench the deal. I never saw Pearl wear that hat, but it showed up in "Happy Anniversary Gough and Jessie," and "The Three Astaires" being worn by Edie Pegden.
I also noticed that in "Extra! Extra!" Foggy is wearing a black hat, in a smooth cloth fabric, that matches the outfit he's wearing for the film. It is identical in design to the wool tweed hat he usually wore.
Nora was often seen wearing her hats front to back. She had a blue hat and another pinkish color hat that she wore with the flower in the front, then the hats were turned around and worn with the flowers in the back. She did that with several of her hats.
Can't remember the episode, but another actor is seen wearing the same type of cap that Eli Duckett always wore.
I'm particularly fond of hats for church and dressy occasions. My wish list this year includes buying a traditional Stormy Kromer cap.
