OK, this aircraft was a fighter, but was often used for other purposes. It was both single and twin seat, and it changed engines several times. It was also a floatplane, and a civilian tourer.
For it's time it was one of the best, but the original production version was produced in small numbers, due to engine supply problems from RR. A new engine was sourced, and the airframe slightly altered. This was so successful that the American, British, and French wanted it, and the American to build it, along with the British original company. This wasn't surprising, as it was one of the best of it's day, certainly one of the fastest, if not the fastest.
Huge numbers were ordered, too much for this company, so sub-contractors were brought in - and then the war stopped, after just a few were delivered. Sadly the company folded a few years later. Interestingly, it had a new life, as the people who bought the assets saw the potential, and it carried on for a while, under a new name.
Countries that used it include:
Belgium, Bolivia, Canada, Finland, Ireland (including one for a very special personal purpose), Japan, Latvia, Lithuania, Poland, Portugal, Spain, USSR (100 copies), UK
