Grey Baby Rolleiflex

The Baby Rolleis were designed for 127 (4 x 4) film and are scaled-down version of the 120 models. The one here is a late (grey) model from the 1950s. At the time of writing, it is the only 127 camera in my collection, and I don’t intend to add others unless they come up at very good prices!
