Maintenance crew checking and reloading Me 109 guns.I wonder what the guy sitting in the cockpit is holding.At first glance  it looks like a gun,but then what would it do there?These photos come from a great site but sadly there are no captions with the photos.So please correct me if my interpretations is  are wrong!Greetz,Brummbar
