Hi Dave,
Philippe Couderchon was the man who direct the cokpit restoration from the French He 162 at "Le Bourget" Museum and who is now helping for her "skin" restoration.
Philippe was kind enough to give some replies to my question on aerostorie forum (a French speaking forum:
http://www.aerostories.org/~aeroforums/forumhist/ )
- He explained he was lured with some yellow paint between two panels but he is now pretty sure W.Nr. 120015 is actually "white 21".
- Further more in 1947 The French took off the German painting but luckily they kept some markings and especially the diving eagle emblem on both side of the fuselage. Cant wait to see some photos...
- He also said that some emblems had been painted by Germans after Leck surrender! Incredible no?
Cheers, Olivier
