I get torn over whether or not it should be restored further. Seeing it on it's gear and intact also has an appeal.
I don't see any real possibility for that because of the reasons I mentioned. Admittedly, the aircraft nut in me would really like to see an intact Brewster aswell...and one screaming past the flight line at 450km/h in a Finnish airshow.
But BW-372 is quite unique because of it's history, condition and the fact that it's 100% original. So it really would be tough to restore it further as there isn't really nothing left to do that wouldn't destroy the signs of the plane's history. Well, one thing could be done is to raise it on its gear like you mentioned. That alone wouldn't really hamper the plane's originality and AFAIK it was actually the original plan with Finnish Air Force Museum and Pensacola but it was later decided against it. Personally, I prefer it the way it is displayed, on its belly. That way the display can show much more of the plane and its details to the museum visitors.
I've not heard what the plan is when and if it goes back to Pensecola. I'm of the belief it should stay in Finland, but I'm guessing the US Navy folks might not feel that way.
I probably don't have to mention where I would like the plane to stay, but it is now property of the Pensacola's Museum. While Finland is a country with excellent standards of living, it's a very very poor country when it comes to goverment funding of projects like this. When the search for the BW-372 was planned and started the funding came from the United States, and the plane was going to Pensacola from the start. Funding just wasn't there in Finland.
I comfort myself by thinking that BW-372 will serve as quite "a calling card" of the Finnish Air Force's history on that side of the pond and tell a story of our small country in the process.
...and Btw, thanks to HTC and Greebo BW-372 flies again!
