Little known trivia! While working for Champlin Fighter Museum I spent 4 1/2 years rebuilding his TMk-9, MJ772 after a landing accident due to a broken pneumatic system. Both TE-308 and MJ722 were in the movie "Battle of Britain", both those A/C were shipped to Canada and sold to parties in the US. When the two A/C were assembled the wings were swapped by mistake, which we discovered during the restoration. Bill Greenwood was buying TE-308 from Woody & Chris Woods about this time, but had no interest in swaping them back. As I remember MJ772 had at least 4 confirmed air to air credits during the WWII. Both were converted for the Irish Air Force as dual control trainers after the war.
Well not quite.
I personally shipped TE308/163 over to Don Plumb in Windsor Ontario in July 1970. Then it was the first time the wings had been off the aircraft since it was in service with the Irish Air Corps. It flew over from Ireland for the BoB film.
MJ772/159 was retained by Willy Roberts who later sold it direct to Doug Champlin, in the US in 1974.
If the wings were interchanged it must have been done at some time in service with the Irish Air Corps. Because of the spar fixings and oversize bolts I can can see no logic for even considering this.
