About this detail of the Tiger
The Airfix kit #1363 has two paint schemes, both of them for the "Das Reich" division. That unit fought in Russia in 1943, and in France the following year. Airfix have labelled their paint schemes "Russia" and "Normandy".
Airfix tell us to use the same decals for both schemes, including the turret number "823". They believe that a specific Tiger served in both locations. But this is impossible because "Das Reich" didn't bring their "Early" Tigers from Russia to Normandy. They got new "Late" Tigers there.
Is the "Normandy" scheme valid? Is it possible that Tiger "823" was shipped to France? Actually, we know the fate of Tiger "823". It got renumbered as "S24" and took part in the Battle of Kursk, where it was severely damaged, with penetrations of its hull. It cannot have remained in service after that; and in any case, the unit was no longer using "8xx" numbers so there was no "823" in Normandy.
The kit's "Normandy" scheme is a fantasy, despite Airfix' "workbench blog" saying that this Tiger was in France "just prior to the Allied invasion".
What about the other paint scheme? Tiger "823" was in Russia and took part in the Battle of Kharkiv in early 1943, when it was numbered "832" and completely white. After the fighting, "Das Reich" rested and painted their tanks. Around April the new number "823" was written over the old, just like in the kit's decals.
But this "Russia" paint scheme is faulty. Airfix specify two colours, tan and "German grey". In reality, Tiger "823" never had grey paint. Documents and photos agree that the Tigers in "Das Reich" were brown at first (RAL 8000), then whitewashed, then repainted in the Spring. The standard three colours of the time (tan, red and green) were apparently used.
However, Tiger "823" was a special case. Its crew cleaned off the whitewash, then incorporated the old brown paint into the Spring pattern. This is why the old number "832" can be seen under "823". Unfortunately there are no colour photos to show us exactly what they did.
On the topic of colour; note that the wheels of the Tigers in "Das Reich" were always covered in mud.
