"MO" stands for "Model." Though it's possible it has to do with a zip code since McGucket's Conspiracy Corner seemed to suggest that it had some greater meaning behind it. Problem is 52584 is the zip code for Pulaski, Iowa. Don't know why you thought it's for Missouri. It's definitely Pulaski, Iowa. Pulaski, Missouri isn't a town. It's a county so it doesn't have one specific zip code.
