I love plus 60 years old optics and I worship the designers for how much effort and intelligence and experiments they put in their design, ergonomics, glass research, optical technology, mechanism and tooling expertise. And I love the design trends of 30s like streamlined race cars, motorcycles, fashion, jewelry,furniture ,architecture, literature, art . I love the exact qualities of these cameras.
So I use, used these cameras whatever reason a museum sees it to be needed to be collected.
