Actually no Krusty. My original panel line and rivet layout was for an all metal Il-2 as that's what the diagram I was using showed. But then I did some research and realised that most of the Il-2s built during the war were of partly wooden construction.
The first production single seat Il-2s were indeed all-metal aircraft. However early in the war, as there was a major shortage of aluminium in the Soviet Union, Il-2s got a wooden rear fuselage. Later on the outer wings were made from wood too. By late 1944 the metal shortage had eased and aircraft with metal wings began to be produced and in spring 1945 some Il-2s were built with metal rear fuselages as well.
Most of the Il-2s that survive today are all-metal aircraft which is why most of the panel line diagrams show this configuration. This in turn is why so many profiles show metal rear fuselages. However metal wings on front line Il-2s were uncommon until well into 1945 and metal rear fuselages were rare until much later.
The photos of this aircraft were taken in January of 1945, they clearly show a wooden rear fuselage but don't show the wing construction. I'm assuming it had a wooden wing, as this is more likely at this time. However I still have the metal wing panel line and rivet layers if I need them.
