Gentlemen,
Something for you all to ponder, I recently bid on two Blueprints on EBay and today they arrived in the post. I bid on them because one was for a Lister, I thought an L type, now I have it and have been looking at it closely.
It is not an L type but I think either a R or Q as the flywheels are 31in dia, by the design of the engine, which is headless it is pre 1930's. This blue print was supplied to W Armes Ironmonger Boston Lincs as a foundation plan and it shows the size of concrete base, water tank etc. The really interesting bit is what is fixed to the wall, a gas bag and pipework which is then connected to something identified as a Gas Valve with an Air regulating c*ck instead of a carburettor. What knowledge of Listers I have learned and read running one on gas is not part of it. Does anybody have any views of which I would be very interested.
