These pitons have no markings. I identified these as Salewa pitons based on these very same pitons being listed as Salewas on Marty Karabin's web site. He based his identification on Salewa pitons shown in the 1980 Stubai catalog, but noted that the photos in the catalog listed as Salewa showed Stubai markings.
