Foth Derby (II, w/CRF)

The Foth Derby II with coupled rangefinder is a compact strut-folding camera that takes 127 roll film, a format common in the small-camera market of the 1930s. It was positioned as a pocketable rangefinder option from the German maker Foth, sitting above the simpler scale-focus Derby variants.

Inspect the focal-plane shutter cloth for pinholes and check that slow speeds run cleanly, as 1930s shutters often need service. Confirm the coupled rangefinder aligns both vertically and horizontally, and check the folding struts for play, since bent struts affect film-plane parallelism. Spares are not commercially available, so condition and completeness drive what the camera sells for.
