Hello kaima!
I've been working at the museum seven years now and it still looks same to me. When it arrived to our museum, it was already spent almost ten years at the surface, so the colours should have been neutralized already. I'm not sure what Kai meant.
There was some amateur restoration already made when the Hurricane arrived to our museum for conservation. The fresh light blue and some yellow on the fuselage has been painted by someone when the Hurricane was storaged at Vesivehmaa, I think. We made some careful sanding when we removed the grey paint layer covering the swastikas. The newly painted swastikas has been painted on removable layer. Also there's few reproduction panels which were painted with modern paints and mixed the colour as close as possible to the original. For example the covering panel of the left outer wing seam.
