Roses I should check "Gisela" against: * Shady Lady * Encore * Else Poulsen * Kronprinsesse Ingrid * Little Miss Muffet * Tom Tom * Lady Maysie Robinson (Kordes) * Adrian Reverchon, Lambert 1909 * The Doctor, USA 1936, making it highly unlikely * Erfurt (hot candidate), has very dark new growth, Kordes 1939 * Margaret * Queen Elizabeth (too many petals) * Eiffeltower (petals too soft?)
However, the most obvious guess would be a popular German rose, possibly Kordes or Tantau
