Weekend Steam

 Avery produced traction engines in three basic styles. They made return flue engines with the engine on top of the boiler, undermounted engines with a double-simple engine mounted on a frame underneath the boiler, and traditional traction engines like this one, with a locomotive style boiler, and the engine on top. The firebox door is a fascinating piece of machinery on Averys, and the feedwater heater on the left side of the boiler is distinctive.
