Unfortunately the Spirfires we had at the Museum for years all departed for home a couple of years back.
I can get pics of OTHER planes' solutions, but the British typically do things slightly differently than, say, the Japanese. I say that because the Mitsubishi Zero control surfaces are being recovered and can be photographed so the trim mechanism is evident at this time. But ... no SPitfires around to take pics of at present. Probably will be in early May when we have the airshow, though ...
