StoneRoad2013's photos with the keyword: 'Simplicity' roller

A very nice model of a Wallis & Steevens "Simplicity" steam roller, note the steeply inclined boiler. This design feature makes it very difficult to get into a position where the water flows away from the top of the firebox [aka uncovering the crown of the firebox] which could be very dangerous, and with a high risk of causing serious damage.
