Here are a number of pictures of the Stampe SV.4. I'm not too familiar with this type, although as one commentator [at the flying display] stated, it looks similar to an DH82A [Tiger Moth]. Perhaps, if you don't look to closely at the tail, the wings or the fuselage [did I miss anything?] :-)
The aircraft was put through its paces several times during the day. Here are some of the pictures, including takeoff, in formation with the Tiger Moth, during the ribbon cutting demonstration, and a few other pictures. If you look closely at the pictures you'll notice that the pilot is sitting there without a headset or helmet [but at least with a windscreen]. This looks like real flying! Wikipedia has some more information on this type.
