Hello Rafael,
Metafot was a manufacturer. The owner was Lutz Hielscher, who later sold the company to produce beautiful steam engine models of his own design in a former small locksmith's shop. Mr Hielscher had to give up this business two or three years ago for health reasons at the age of 80. Both Metafot and the small manufactory were based in Wuppertal, a town in the Bergisches Land, Germany.
