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.

Sales data for this model is thin: a single UK auction hammer result in early 2026 saw an example sell for £38, so today's value sits at the lower end of pre-war folder territory at saleroom level. With only one recent wholesale data point, buyers should treat that figure as indicative rather than a firm market price, and clean working examples with a functioning rangefinder may achieve more.
