I think the most likely candidate is Groupe de Reconnaissance GR.II/33 Savoie which converted to P-51s in February 1945 possibly taking over a/c from the 111TRS. It seems they were based at Luxeuil and or Colmar during March and April but I have not worked out whether that puts them close to this incident.
