Air Masses And Fronts (1943) - Armed Forces Shorts Theatrical Cartoon Series

I saw this animation movie in 1956 at the age of 8, when my father, a Belgian military pilot and instructor used it to teach meteorology to Belgian pilots. Today, I teach meteorology to private pilots in Norway and I remember with great passion this wonderful movie from Walt Disney studio. I remember how the flat shape of a warm front was illustrated as a paintbrush being drawn, and the curly shape of a cold front, by a paintbrush being pushed.
Unfortunately this movie has never been digitized or made available to the civilian public. If anyone knows here I could purchase a copy, please send my an email.
Kind regards,
