This fair was the key public display, by [[Chemische Fabrik Griesheim-Elektron]], of an Adler 75HP engine with a cast magnesium alloy crankcase.  This alloy was the notable [[w:en:Elektron (alloy)|"Elektronmetall"]] first developed by [[Gustav Pistor]] and [[Wilhelm Moschel]] ("Elektron" later becoming a British-registered tradename for a range magnesium alloys manufactured by the British company, Magnesium Elektron Limited).    

Also exhibiting was [[August Euler]] (1868–1957), owner of German pilot's licence No. 1, who manufactured [[Voisin]] biplanes under licence in Griesheim am Main. His [[Voisin]] biplanes, with [[Adler]] 50 hp engines, flew in October 1909.
