This scheme represents the Buchon "Yellow 10" as painted for the file, "The Battle of Britain in 1969".
Hollywood produced an epic back in 1969 with no CGI. They weren't proper 109's but for most of us they made do. To the purist a Buchon is a Buchon and not a 109. But for those who want to recreate the "Battle of Britain" feel this mask set is for you
