    Hello friends of stationary engines :p

    I have bought an National gas engine in Germany.
    Now I am looking for informations about this engine.
    What is the year of production?
    How many HP?
    What means the "P" next to the serial number?
    Thanks for your help! :)

    Hallo Thomas,

    What is the bore and stroke?
    I have a list here so we can figure out the size.

    Hello Hubert :)

    The bore is about 5,9 inch.
    The stroke is about 10,25 inch.
    The dimensions are not exactly, ony nearly.

    Thomas :wink:

    Hallo Thomas,

    Those sizes do not correspond with my list unfortunately.

    The nearest are:
    5 x 9" which is a 10 hp engine @ 600 rpm with a weight of 1740 Lbs
    5,5 x 9" which is a 12 hp engine @ 600 rpm as well and an weight of 1790 Lbs

    The next size up is a 6,5 x 12 " engine and I don't think it is that big.

    About 10/12 Hp looks right for your size of engine.
    I am surprised about the high revs for an engine like this. I checked other makers of the same period and they usually quote about 450-500 rpm for engines withe the same rating.

    Beste Grüsse,

    Hi Thomas,
    You need to email Mr Challinor at The Anson. He has the remaining National records.

    Hello :)

    I wrote to Mr. Callinor 5 days ago-No answer till now.
    Perhaps he has to much work into the Anson museum.
    At the WICO magnet the electric contact was not at the place he has to be. So I built a bridge to the place were the wire comes into the magnet and so the spark is there.
    Now the engine is running!

    You can see on :arrow: YouTube.

    Best regards :wink:
