    Description

    From my small patent model collection I’m selling this unique antique steam engine slide valve model.
    The patent dates from 1868 and this model was made by G.W. RAWSON Cambridgeport MAS. USA. No tag, sorry.
    According to the patent text it has a spring loaded tripping twin shutter port valve mechanism.
    As pictures show it’s hand cranked and it works perfectly.
    Made of mahogany, brass and steel.
    It measures ±25 inches long. (62.5cm)
    All parts move freely and from what I can see it’s in great condition for a 153 years old model.
    It comes with a clear patent copy.
    Please take a close look at the pictures and if you have a question please ask before you bid.
