The "pea dot" (Erbsenmuster) camo in your sample photo is a 44-45 pattern, or a touch after your stated date.
German uniform camo went through a bunch of iterations, and there's overlap for some.
For '43 you probably want an "Oak Leaf" (Eichenlaubmuster), but that's also an awful thing to paint for all its soft edges and blurry color demarcations.
Now, an argument could be made for "Plane tee" (platenenmuster)
There is the issue that, mostly, only the Waffen SS used camo, which can limit what you are depicting, too.
So, the Luftwaffe's splinter pattern (splittermuster 41)
Could be an option--this is not an ideal patter n to try an paint in model form. Those needle splinters are very tiny.

And, there are those who will argue all different sorts of ways on this topic; peoples' prised oxen are easily gored.
And, as always, this is all down to what you want to depict.
