This is a fairly simple camera, mainly bakelite construction, but it gives very good results. The two scale focussing lenses are coupled together, and it has a feature that a lot of other cameras could benefit from: there's a spirit level built into it, which is visible in the bottom of the viewfinder, so there's no excuse for ever taking a slant photograph!
