Voigtländer made two TLRs, the Superb and the Brilliant. The Superb is a killer of a camera, and even now they're hellishly expensive. The Brilliant were the economy line cameras. The first version, which is what I've got, came out in 1932. Technically, it's not even a TLR, since the upper lens can't be focused (thus it isn't a "twin"). And there's just not much to it. Later Brilliants truly had twin lenses and the upper lens could focus, which made them more useful. What I always thought made these later models truly nifty (and mine does not have this) was the side compartment where a couple of filters were tucked in. How cool is that?
