This is a small, handmade model of a Triplane. The fuselage is an old spark plug, which has been welded to other bits of scrap metal to form the wings, propeller and undercarriage.
This is a nice example of spark plug art, which is usually created by bored welders on quiet days. Most of the spark plug aeroplanes that we see are biplanes, so this is a little more unusual. The Triplane is famously linked to Manfred von Richthofen, the Red Baron, the legendary pilot of the Imperial German Army Air Service during the First World War.
What condition is it in?
