Colour slide film, would be I think, slower in film speed,
at that time. Maybe 80 ASA?

Yes actually even less than that Agfachome used to be 50ASA and Kodak did
Kodachrome which was available in two flavours 25ASA and 64ASA and I think
Ektachome was available at 64 ASA. That said there was also a film made by
GAF Ansco which was 500ASA if I remember rightly. GAF film was fairly
popular and readily available to amateur photographers through Camera shops
and large departments stores and presumably was available throughout Europe
particularly in affluent popular tourist destinations such as Switzerland
and Austria because of the Alps, Liederhosen cheese with holes, sausages,
singing Nuns, beer, and not to mention flying saucers :)

But yes in general the most popularly available 35mm slide film was a bit
slow back then. But even 50ASA film will allow shutter speeds in the region
of 1/60 at f11 in average bright sunlight and for general photography one
wouldn't need anything beyond 100ASA. in fact some cameras weren't capable
of using  fast films without some manual conversion and guess work. Though
the Olympus ECR had a top shutter speed of 1/800th second so should have
been capable of using faster slide films up to around 500ASA and many
cameras of that time were made to be able to use film up to about 500ASA
since B/W film up to 400ASA was fairly common and readily available. :)
