Luftwaffe flight log book or Flugbuch to a Stuka pilot

Original Luftwaffe flight logbook or Flugbuch to Johannes Lüdewig. The last note dates 26.6.44 ‘Vom feindflug nicht zuruckgekehrt’ indicating he didn’t come back from a attack. Most of the bases he flew from are in the Chezch Republic. This is a good base for further research and should be researched!
