??????
could be Marvic or Tecnomagnesio in Italy ?????
But could be also some UK foundry ???? Crosthwaite and gardiner ????http://www.crosthwaiteandgardiner.co...che-parts-list
They are black treated ...... from what I know Marvic deliver only in gold painting but I know the factory being equipped with this specific magnesium black treatment ( in french ; "Mordensage")
