The Italian Buick Mystery

Recently we were shown a Buick brochure that was published in Italy. So far, so good, but the models shown had us confused. The sedan looks to be a 1920s model, but apart from the Buick logo, it's one we have never seen before. The pointed radiator and sharp looking bodywork is something we have never seen before on a Buick. Apart from the sedan there's also a frontal picture of what seems to be a roadster, however the brochure doesn't mention any dates, nor manufacturer of the coachwork. We know that Buick had a Spanish connection with the Abadal-Buick, but we have never heard of an Italian connection. Who can tell us more about these Italian Buicks?
