First, while i know that some D series were remanufactured from A series airframes and some were purpose built as D's, i was wondering if anyone knew what the actual production figures for each were, as well as which A types were used and if there was a relationship between type of A model and type of D model, also what happened with the werknummers in the case of remanufacture.
And second, I was wondering if anyone had more details about the raw aluminum undersurfaces of some late war 190D and Ta152 wings, i.e. quantity, number of factorys which did this, exact borders, etc. Thanks and I hope it is ok to have 2 different questions on 1 thread.
