Here are completed pictures of my Ju 390 in 1/72 scale. The model was constructed using two Revell of Germany Ju 290 kits. It represents the Ju 390 V2 developmental aircraft serving FaG 5 at Mont de Marsan in France during the Spring of 1944. Even in 1/72 scale this is a large model with a 27.5 inch (69.9 cm) wingspan. Research and construction notes are posted in this blog.
