A British Curtiss conversion would be a multi-year Blackburn test programme

If Britain bought the Curtiss SO3C aircraft for conversion, who would do the work and how long would it take?

Blackburn is the likely contractor, and the design and testing effort would take at least a few years.

Blackburn is identified as the most likely British firm to receive the work. The conversion and expansion effort would take at least several years. Buying the entire American batch could shorten the calendar only if the extra airframes and funding supported a much larger test programme. Adaptation time depends on the intended pace and scale of testing, not just the number of donor aircraft.
