This is a very old metal Masonic Perpetual Calendar. It is 4 3/4" tall and 4" wide. You can set the month and turn the dial to accommodate the days every month. My dad was a Mason for most of his life and this was on his desk. (I don't think he ever moved the months though.) It does turn quite easily though. Get some early Christmas shopping done for someone who is a Mason, or collects Masonic items.
Check out my shipping policy. It's different than anyone else, I think.
