I have some really old Salewa tour bindings (but not as old as Ramer) if you are looking for something like that? Not at home for a few days but like this: https://wildsnow.com/backcountry-skiing-history/binding-museum-backcountry-skiing/salewa-tour-1987-backcountry-skiing-alpine-touring-binding/
currently mounted on some kids skis with skinny skins but they work pretty well for easy stuff. I skied from Camp Sherman on Rainier with them one.
