Yep, Harrison and Jamie got it. It's a B25C Mitchell II. This is the one which becam known, in the UK, as Grumpy. The pics were taken circa 1988, just after it arrived at Duxford, UK, before being painted in RAF colours. The aircraft is rare in that it was actually one of a batch to serve with the RAF, although most of the war it was in Canada as a training aircraft. Got the serial and details somewhere!
It is now back in the USA, having been exported at the end of August last year. Pics show the full image of the previously posted area, and what she looked like before being painted.
Harrison got it first, so post a pic H - one of your own. Actually, I'll leave the decision to gary, as Harrison had a stab at four aircraft! Perhaps jamie should post?
And BTW H, you're building a B26, so you should see that it doesn't have a slab-sided fuselage!
