In 1933-1934 Tibor Takátsy, who worked for Magyar Acélárugyár (Hungarian Factory of Steel Goods) the parent company of Méray Motorcycle Co designed a chassis with a three-cylinder radial engine. Nine trucks and one passenger car was completed. The puzzle picture shows Endre Méray-Horváth with members of the family Méray family and the mysterious passenger car. There were three other photos known but those have disappeared in the last 20 years and only a colour photocopy remains of those.
