They were marketed in the USA in the late 1980s-1990s. I saw them on display at the big Photo Expo shows in NYC at the time. They were system cameras, designed for the advertising studio market. Competing against Sinar, Linhof, Arca-Swiss, Toyo, et al. I had their brochure, which showed many studio accessories, a la Foba; stands, tripods, booms, etc.
I never knew anyone who used one, and the ads disappeared from the magazines rather quickly. So despite their apparent quality, they must not have been a sales success here.
