Italeri kit has very good fit despite to his age. Only minor issues I have with roof, and I need to sand two montage pins for good fit. Sanding on nose was quite easy. At first quick set glue. And next a little bit of CA glue as putty. Sanding by Vallejo sponge 600/1000, and rescribe panel lines by hobby saw. For better results I made flaps ailerons and rudder as leaning out. I learned that Junkers Flaps was unique Junkers patent and is used in modern Junkers sports and tourist aircraft to this day. Also air intakes I drilled and glued to fuselage in drilled holes for better strenght of glue seams. Main undercarridge was glued in drilled holes, and only minor liquid putty were needed.
