I made this engine many years ago and thought that it might be of interest for you to see the way it is constructed. It is nearly all brass which I have given a flash of gold to stop it tarnishing, I have never had any success with laquering.The scotch crank yoke runs in two small ball races which I have omitted to show in the pictures, the piston is cast iron with an aluminium inner that holds the gudgion pin, the base is slate.
