This is a twin cylinder version of the popular 'Hotspur' single cylinder engine.
The bore and the stroke are the same as the single cylinder 'Hotspur'. The open ended cranks are to 90' to each other to enable the engine to start in any position.
There are also provisions made for fitting an axle driven water feed pump, and a governor.
The base is offered separate from the main engine castings so that modellers may, if they wish, use a wooden block with a 1/8" BMS bed plates which keeps the price down.
The cast aluminium base is offered with the top bed plate surface machined flat.
