65 Commando stock brake set up

My 65 Barracuda is a true Commando motored car, but is not a Formula S. These are the front drums that are on it. Someone else may know what they are by looking, but I don’t. They will be getting replaced by BBP disc’s when I pull it apart and redo it. These just keep it a roller until then!

Those look like 9" drums to me
