Figured some here would be interested to know that Spitfire Mk.1 X4650 recently took flight for the first time following the completion of its restoration. Some early images/discussion can be found here: http://forum.keypublishing.co.uk/showth ... p?t=115420
This brings the total of flying Mk.1's to three, and that doesn't include the BBMF's Mk.II. The aircraft is currently based at Biggin Hill, owned (or at least in the care of, for the time being) by Peter Monk. And this is far from the last Mk.1 that will be increasing the number of airworthy examples in the years to come.
For those wondering, she's finished in the same colors she wore in 1940. More information on this specific aircraft can be found here: http://www.telegraph.co.uk/history/batt ... ation.html
(Al Deere's Mk.1, X4276, also mentioned in the article above, is said to be under restoration to airworthy condition too)
Here are some images from the last year or so, showing the restoration work in progress at that time: http://vmiengineering.com/Spitfire-Mk-1-X4650http://www.flickr.com/photos/dwhitworth/5785715463/http://www.flickr.com/photos/dwhitworth ... otostream/
