YEP !
In just published French mag "AFM", for Aviation Française Magazine, N°6, Philippe Couderchon tell us that 120015 was actually "yellow 21"
She was first thought to be "yellow1" since during her first restoration in 1976 they were only able to find Wk.Nr.120023 on the tailplane but as for "white4" it was not her original tailplane
