In 1943 five Spitfire VIs (
BS106,
BS124,
BS133,
BS134 and
BS149) were converted to improvised PR Mk VIs by
680 Squadron in Egypt. These aircraft had been "tropicalised" using the same bulky Vokes filter and other equipment used by Spitfire VB Trops, as well as being painted in a "desert" camouflage scheme.
