All, thanks for taking the time to respond. I have taken parts of the cast iron top in for repair and unfortunately can't take pictures of it; wasn't smart enough to take all inclusive pictures before taking pieces in to be fixed or replicated. I had heard somewhere that M&S bought pumps from the Saint Louis Company but can't verify. Mr. Sims, can you please post the picture of the square M&S Square you mentioned above? I have googled this pump in every way possible and cannot find anything. Phil, will come to visit soon to get pictures of your base. Again, sincerely appreciate all of you taking the time to respond.
