At some time when the Vizard unit is on display, there could be an area for aviation artists to display their work. For a start there would be a place and time where my own pic might earn some money and the artists could make a donation for their publicity opportunities. The society of aviation artists could perhaps promote themselves. There could be a closed session for drawing of photographers working for aviation magazines and their content would give us more publicity. Steam organisations charter photo sessions. There are a couple of lesser problems: one is the time to completed painting (take my example) and secondly, artists always have to find a means of transporting their pictures to an event and therefore insurance may raise it's head. Modelling the Whirlwind could be another idea. 

We now need a list of other, better ideas, like contacting/visiting people who have experience in funding methods (like the railway preservation people, who've been raising enough for new build steam engines and bridge restoration, moving signal boxes and all sorts. Joining in on other events would bring in more contact with the public. Could the Whirlwind spend a month at the Royal Airforce Museums (with canopy locked) but videos/talks about Whirlwind activities. Proceeds shared between us and the host. Anyway, think outside the box. Museum of London have visitors paying to join talks normally based on videos but they could be based on artifacts. Importantly, cakes and coffee downstairs.
