Hi, I have a National Oil Engine built by The National Gas & Oil Engine Company. On its identification plate: Type MB, 17 Horsepower, RPM 400, Serial number: 51861. Can you please help me with some more information and the year of manufacture? I live in South Africa and also on the engine is that it was imported bt WM Spilhaus & Company.
Hello, I am told that dating a National is usually not going to be precise due to lack of records. I have a model KB diesel and was led on to the Anson Museum http://www.enginemuseum.org/ and they were able to give me a range of years of manufacture. Have you looked hereon this site for a manual? Good luck with it, Butch
