Yes Jack, the information from your book was about all I could find on the Birmingham Machine and Foundry Company or "BMFC". You have two illustrated pictures of Birmingham pumps. One is a 10 gallon model (401D) and the other is a 5 gallon model (400-UD). Mine is identical to your 5 gallon model but the model number on its manufacturer plate says 300 R. I read that prior to construction of gas pumps the "BMFC" primarily constructed heavy equipment for the sugar cane industry. Thanks for sharing all of your valuable information. Tony
