We just received some interesting information from our intrepid volunteer Gerry. He has been researching our Worthingtons and recently had a discussion with somebody he considers the foremost expert on steam pumps. He confirmed that Monitor‘s Worthington pumps are believed to be the oldest examples of Worthington manufacture. Further, they are probably the oldest direct-acting reciprocating steam pumps in existence! If you have any information that proves us wrong, please contact us — we’d love to hear from you.
